Acorn Cottage Roof

photo copyright Karin Corbin 2009

I have been busy with things other than miniatures this week but I am posting a few photos on how I made that unusual roof for the Acorn Cottage.


The beams which support the roof have a curve to them which creates the curve for the roof. Putting it together is the tricky part. The beams have to be held in the correct position in a six sided radial pattern. So I made a custom assembly fixture. It is not pretty, just made out of scraps I had around the shop but it works great.

The plywood I used for the roof is thin, it will curve in one direction. Getting it stuck to the beams without using clamps was the tricky part. For this task I used polyurethane hot melt adhesive that comes in cartridges. The glue set up in a 90 seconds so the pressure of my hands holding the panel against the beams was the clamp.  This polyurethane glue gets harder as it ages and it cross links with the wood fibers. This is probably not a glue and gun you will buy for the occasional job, the glue is expensive, the dispensing gun is expensive and the glue has an expiration date. I purchased my kit from ROCKLER

You can see the beams inside of the roof. The opening is finished off with a strip that will be grooved to accept thin, clear plastic to close the house off from dust and unwanted intruding sticky fingers.

The roof plywood is so thin you can cut it by scoring with a knife. I made a pattern for the shape and also a stencil to mark the rows of shingles. I marked the rows before I assembled the roof. You might think that because the plywood is thin the roof is not strong but it is. I used to use heavy plywood for dollhouse roofs but I realized as long as there are beams to help with support  thin plywood is adequate and it is much more in scale. The look of the roof edge is nicer and it weighs a lot less. I created a wavy curve in the edge of the cottage roof to resemble the loose shape of the lower edge of the leaf canopy on a deciduous tree. The Acorn Cottage is very organic in its various elements.

The leaf shaped shingles I used for the roof are one of the unique features on this cottage. They started out as normal rectangular dollhouse shingles. A pair of scissors is all that is needed to trim one end into that point. Boring work but just fine for TV watching time.

Using Calipers

photo copyright Karin Corbin 2009

A tool that gets used all the time in my workshop is a digital caliper. They range in price from several hundred dollars for a very high precision unit to about $30.00 for a unit that is just fine for  most tasks in house holds or the average home workshop.

You will see two of my calipers in the photo above, the one on the top is by Mitutoyo, I have had them for a number of years and use them for tasks in manufacturing workshops where precision is important. The caliper at the bottom of the photo is a pair from WIXEY I purchased about 6 months ago, it will read in fractions. Most fraction reading calipers are not very accurate but this pair is reliable in that you know there is only a four thousandths spread in which it will read the fraction. Huh you say? OK so a 1/4" in decimals is .250". The caliper display reads 1/4" in fractions anywhere between .248" and .252".  Plus or minus .002 (two thousandths) of an inch is not an uncommon tolerance in manufacturing. But in miniatures you can see that gap if you are looking for a really snug fit. Most inexpensive digital calipers that read in fractions are not all that accurate, the Wixey pair is very nice quality.

So the conclusion is that fractions are OK to think about in general terms but working in decimal inches or in millimeters is way easier for math and digital calipers are so easy to use it makes no sense to me to worry about trying to mark or cut something to 1/64" or 1/32" and then read it off a regular ruler. It does not take long to memorize .25" or .50" or .75" or .125" instead of the fractional unit. If you can't remember there are a lot of free charts you can print from the internet that show the equivalent decimals, fractions and millimeters. I have a few of them around the shop for quick reference.

In the photo below I am measuring an inside dimension. I am going to divide that result in half and mark the centerline for my muntin location to divide up the panes in the glass area on the door. You can see the prongs on the caliper I am using for an inside dimension, I just slide open the caliper until they touch the wood.  I  look at the display to know just how wide that distance is. I love it, so easy on the eyes, no strain trying to see a the tiny line reads on a ruler and then try to see the tiny marks to figure out what fractional division it is by counting the marks. With a push of a button I can display the dimensions in millimeters instead of  inches.  On some calipers I can also read the results in fractions. But I personally almost always work in thousandths of a inch. This is a real time saver way to measure that also increases the quality of the miniatures.

In the photo below I am measuring the outside width of the door. You can see the edges of the blades I am using for this task.

In the photo below I am measuring the height of an object. The flat blade is placed against the table and you can see the flat edge of the blade that sits on top of the object.

In the photo below I am using a small protruding pin at the end of the caliper rule to measure a depth. You can use this method to measure the depth of narrow recessed areas such as a dado groove cut to fit a tenon.

After ten minutes of using digital calipers  you will be spoiled rotten and totally frustrated if you happen to misplace them. They are not just for engineers or geeks and there is no reason to be intimidated by the idea of using this tool, they won't bite you and they make the math very simple.

Its all in the details

photo copyright Karin Corbin 2009

I have been busy the last few minutes sorting through the digital photos I took a couple of years ago in the Normandy region of France. What I was looking for were the details on real life windows from colombages buildings also known as Pan de' Bois, timber frame, half timber. If you do an image search on any of those words you will find a great many photos that people have posted on the internet of this type of structure.

I am going to do very simple muntins on my windows. Muntins are the strips of wood, steel or lead that divide up the panes of glass in doors or windows. The muntins will be glued directly on top of a single piece of glass both on the inside and outside. My task today is to cut the lumber, age the strips, paint them, let the paint dry and then cut and glue them onto the door.

I will also start assembling the wood casement windows for the cottage.

I like the lead flashing over the sill, I saw that detail on many old wood framed windows in France. I have on hand enough thin lead from the old wrappers that covered the corks on wine bottles  to recreate this look in miniature.

Of course I also need hinges for my casement windows, this pintil hinge is so very beautiful, but it might be a little too wide of a design to fit my cottage window frame pieces. I would need to make 16 of them and that is a lot of work. Maybe if the new metal cutting blade I got for my scroll saw works out I can stack cut them in batches. I have been meaning to try that out anyway. If only I had a pancake blanking die for them it would be not nearly as difficult. But I don't have the steel material on hand to make the dies or the jig to hold the saw at a set angle to cut the die. It is something to think about trying but that list of things I want to try is longer than a lifetime at this point. Actually  I have been thinking about this for 20 years and visited an artist studio to learn how to do it. Still not at the top of the list for purchasing the needed items, will it ever be? Maybe I will order the steel for it, I need to put in a order of steel to create metal spinning tool rest. Might as well toss that item in with the order.

You can see a pancake die in the photo of this etsy listing, click HERE

As long as you have one straight edge on your part design you can quickly make thin metal shapes using the die and a press. My workshop mate Don has a press I can use so exactly why am I not doing this? Not a clue other than I need to order an adjustable saw frame holder and they are expensive.

Historic Roche Harbor Hotel

My blog has been quiet for a few days as I have been away from computers and the internet. I went on a short trip to the San Juan Islands here in Washington State, USA. My friends had a few tasks to do on a lovely home up on a mountain. From the house we could see right across the water to the lights of Victoria, British Columbia.

It has been almost a decade since I have visited San Juan Island. On my list of things to do while there was to find one of the old limestone quarries and bring back some rocks for my miniature projects. The lovely old Roche Harbor Hotel in the above photo is located right next to some of the old Lime Kilns.

My rocks came from an abandoned quarry in another location on the island. There were several small cliffs of stone left exposed, all I had to do was pick up small chunks of scree off the ground.

The photo above shows some of my  newly collected stone for the Coastal Cottage, I still have to break it up into 1:12 scale pieces. The color of the stone is going to be perfection, grey with a hint of blue and also some browns. It will blend nicely with the timber frame, stucco, floors, roof and landscaping. The stone will be used for foundation walls, the entry step, the exterior chimney above the roof and also bit and pieces in the landscaping.

Twenty minutes of work with a hammer, cold chisel and tile nippers and I have 1:12 scale real stone!

A tatlented stone sculptor from the Island, Tom Small, told me how to find the quarry. Tom's work can be seen on the internet by clicking HERE. I made sure to visit the sculpture garden at Roche Harbor as well as the local galleries on the island. The local Art Museum had a show of miniature sculptures including several of his pieces. Many of the items were of a scale that they could be used to create a miniature sculpture garden made of living small scaled plants.

Beveling the Inset Door Panels

photo copyright Karin Corbin 2009

I am placing a slight bevel on the two panels that will insert into the lower half of the front door of the cottage. I have tilted my miniature table saw over to about 10 degrees. The exact degree within a few clicks or so is pretty much arbitrary on this project. What I am after is a beveled look to the panel that is not too wide and it creates a width at the panel edge that will slide into the slot I showed you yesterday that I put into the framing pieces.

Mostly what I want to show is one way to do this type of wood cutting task safely. Holding small parts so you can perform some kind of shaping operation on them without messing up your fingers or the part is always something you have to think about. However people rarely show just how they do this, mostly you see how it looks when it is all done.

I have taken the small panels I cut to size and applied double backed carpet tape to them. It the photo above you can see that I have place them right against each other while cutting. That is just to save time so I only have to make half as many passes on the saw instead of cutting one at a time. Then I have adhered them to a larger piece of wood I can easily hold onto and push through the saw. I rotate the panels around four times so I get all the sides beveled. The tape is strong enough for this holding task because and I emphasize this fact boldly here I AM NOT TAKING AGGRESSIVE CUTS. I am only taking a very small amount of wood off of the panels therefore the torque of the saw blade will not throw my pieces into the air or jam them down into the saw blade. There is also no danger of these thin panels slipping down and jamming into the slot next to the saw blade. I don't have to use a tall fence or feather boards to keep these tall, thin panels standing upright because they are stuck to that nice comfy to hang onto 2x2 board. A difficult cut is now very quick and easy to do.

I use double back tape a lot, it is very handy for work holding all kinds of things when a clamp or screw can't be used. I just ran out of tape  with this job so I will drag myself off to get my favorite kind, clear plastic, thin carpet tape from the "Do It Best" Hardware Store. That is a nation wide chain in the USA and they also carry K & S engineering metals as well as Northeastern Basswood in the stores in my part of the country.

To find out if there is a "Do It Best" Hardware Store near you, CLICK HERE

I like this particular tape because it holds firmly but it is not impossible to get your part unstuck. Any tape residue will clean off the unfinished wood with acetone.

I could have routed the bevels on the panels or sanded the bevels into the wood or filed them or even planed or carved them. There are many ways of doing this same task if you don't have a tilt arbor table saw and/or don't like using power tools.

Feeling Groovy


For both the doors and windows on my projects I first have to make the lumber that creates the frame pieces and then put grooves into those pieces to receive the glass or wood panels. This time around I am using poplar wood for the window and doors. Poplar is nice and hard and holds crisp details and best of all it is available at most any lumber yard. Sometimes the poplar pieces look green in color but that green will eventually go away and they will be the normal browns you see in most wood.

To cut the grooves into the edge of the lumber I use an 9/32" diameter, 1/8" shanked router bit. This bit cuts only on the sides, no cutting edges on the top of the bit. It cuts much like a blade on a table saw does.  The advantage of using a side cutting bit in a router table is you are not trying to balance an upright thin piece of wood over the top of a table saw. You will have more control with the router table. The bit I use was sold by Dremel as a #198, Dremel has now discontinued making this 9/32" bit but it is still available online from Widget Supply as Item: D-AL21.
Link Click: Groove Cutting Bit
You will need to make several passes to cut the grooves to full depth. The reason I like the #198 bit is the depth is always the same, you go as deep as the 1/8" diameter shaft allows. When you hit the shaft you can cut no deeper. Another huge bonus of this bit is you can make arched windows by following along the edge of the curved window frame using the shank of the router bit as a pattern follower. The depth of the groove is just enough to hold a piece of glass securely and hide any minor chips on the edge of the glass. The width of the groove can be adjusted by doing a flip cut.

To determine the height from the router table to the top of the router bit first figure out the width of the groove. Now subtract that dimension from the thickness of your framing member. Divide that number in half and subtract it from the thickness of your framing member.  Now set the height of the top of the bit to that calculation. I use a digital caliper to check the height of the bit. If you are using standard window glass or art glass you will need to flip the framing piece over and cut again to get the full width of the groove as the bit is not thick enough. With this method the groove will be perfectly centered in your framing member.

My lumber thickness is determined by the thickness of the glass I am using as is the width of the groove. I am not using micro thin glass this is window glass meant for real houses. Using this glass does push my pieces just above true scale dimensions as to the thickness of the door but it is not something viewers pickup on. The illusion is still there and that is what really matters. When I first began to make structures I was all worried about exact precision of dimensions for doors and windows. What else would you expect from a woman who for many years created aircraft parts where the tolerance of parts was measured in thousandths of an inch? But I learned to loosen up my thinking and my miniature work and instead of worrying about exact dimension I create that which is believably realistic and that which works visually with the project I am making and the materials I am using.

Creating that which is believable requires that you educate yourself by putting thousands of images of the real thing into your brain. Seattle is a long ways from the old buildings in Europe so I still start and end most days by looking at images of old buildings as well as reading about the history of the design and building of them. My bookshelves are located right next to my bed and there is always a stack of books by the table where I take meals and I take books along in my car as well for times when I sit waiting for a bridge to open or want something to read at dinner or lunch while out running errands. Many days of the week I browse the internet collecting images for the reference files I keep on my computer. Twenty years of this daily habit of ingesting images has been a real education in  architecture and structural details. My mind now knows what feels just right and I can design original buildings in the style of old buildings from many areas of the world and from many eras.

Windows and Door

photo copyright Karin Corbin 2007

The photo above is the entry door to the Acorn Cottage, is is a plank door with cross banding. The owl is a brass finding I bought. The door handle I made from a strip of brass I textured and bent then solder onto it etched brass leaves. I purchased the sheet of photo etched leaves at a miniature show. I also used the leaves on the light fixtures for this woodland cottage.

It is time to start making windows and the door for my new coastal cottage. That requires a lot of research and quite a few decisions before I can begin to cut the wood pieces.

I am going to create a few outward opening casement windows. They need the shashes and trim moldings cut to shed the rain away from the opening. These windows are also a good opportunity to add some small scale detailing to draw in and capture the viewers eye and give them a change from the larger textures and shapes of timbers and stucco. The visual animation of hinged opening windows and doors helps to break up the plane of the exterior wall surface. An outward opening casement also allows me to place a table right against the window. Objects on the table will help the viewer transition their interest into the inside of the cottage with a little sneak preview. The photo below shows a real life example with the type of detailing I will make.

The window style above with the dolls in it is what I will be using for the coastal cottage.
The drip edge at the bottom of white window frame will be a challenge to create. Love the French blue color of the sill below the window.


I have roughly imagined a build date for my projects framing of around mid 1600s to late 1700s but the time frame for the dollhouse as it stands will be 1900. Now that gives at least a couple of hundred years of remodeling changes and wear and tear on the building. A lot of things happened to home design during that time span, chimneys and fireplaces changed and windows, doors and hardware changed too.

When you look at the really old buildings you often notice changes in the framing around door and window openings, maybe they were added or enlarged or made smaller or even closed up areas that used to have windows and doors.

I plan to have a few small windows from an earlier era on the sides as well as the casement windows. My centuries of fisherman owners were into salvaging and scrounging for some of their improvements and left other things intact from previous generations. Sometimes the sea washes up lumber for home improvements.

This is a scratch building job, you can't walk into a dollhouse store and buy an odd assortment of windows spanning several centuries that are going to fit into a custom design. Over the years I have made dollhouse windows several different ways and I have a few new ideas for making windows I want to try out on this project. This time around my front door will have window panes in the top half as I want some extra light coming into the interior.

The glass I will be using for my dollhouse windows is clear with little waves and bubbles in it. It was mouth blown in France. Up until about 1930 or so most window glass was made by these methods. Picture windows are a modern invention, old windows are made from small panes because that is the only aviable size the glass came in. If you click on the link below you will see a video showing how the glass I am using was made and why window panes were always rather small.

Update I have finished the door and windows since this blog was first posted. You will see it showing up now and again on more recent posts.

Rope Twist

photo copyright Karin Corbin 2009

I have finished carving the two rope twist supports for the fireplace. I will not be elected as master stone carver anytime soon but they look age and wear appropriate for the structure I am going to put them into. The areas where there is a little crumbling from inclusions in the stone is something I like, it adds texture and interest as well as making the stone look older. I think I might have made the ropes a little narrower but I am out of material so there will be no rework.  Don says they are too big to be ropes in 1:12 scale, they are hawsers, big lines for mooring a boat.

The color of the soapstone is a nice blend with the floor that is going to be in the room.

Now I have more soapstone support pieces to make for the fireplace as well as a mantel piece.

Update to this posting you can link ahead to see these pieces in place. Just click on the line below.

Practicing Rope Tricks


I found some soapstone to use for the fireplace. I want to carve a rope twist detail on a couple of the upright  pieces of the fireplace. You are looking at my practice rope twist carving scrap with all the flaws I made. It is sitting next to one of the pieces I will carve for the fireplace. I love the soft, grey and cream colors and that is how I will use it. If I put an oil finish on the soapstone it is dark grey, green, black, brown and yellow. What a Chameleon this stone is!


I show my practice pieces because I want everyone to realize you don't start out as a master the first time you try something. I expect my practice pieces to look pretty bad overall. But I know what I have learned and if I have gotten enough of a clue to do it right the next time.

I have never carved soapstone before so I grabbed a scrap piece and started practicing. Oh boy do I have room for improvement. Problem one, it is not that easy to get the segments marked out nice and even and then maintain that spacing. Problem two, dust immediately covers over what I am carving and that sure makes it tricky to see what is happening. Problem three, it is  hard to carve perfect rope curves with tools that don't have concave curves. Problem four, no teacher around so this is a slower learning curve. The online instructions I found were of no use for making miniatures.

You can't learn how to do something just by reading a blog although it will give you some pointers in the right direction. If you want to do something you have never done before get out some scrap material, grab some tools and have at it. You will quickly figure out what does not work, that is the easy part. Finding out what does work and then being able to repeat those motions is real the trick.

I am truly enjoying working with soapstone. It cuts with a hand saw, band saw, scroll saw or table saw. It sands nicely too. You can detail it quickly with swiss needle files. That feels more like erasing material than carving stone. Using carving knives is tricky as you can flake off chips you do not want to remove. The needle files give better control for fine detail. A final sanding can be done with diamond coated needle files or wet sandpaper. I find it easier to carve soapstone than it is to carve wood so be sure to try it sometime. Fireplaces, fountains, stone sinks, miniature sculptures, bathtubs, doorsteps, stairways, counter tops, tables, benches, you can make any of these in real stone with just a few basic tools.

After measuring a few real ropes I realized that the lines are placed at 45 degrees and the width of the individual diagonal twist section  is very close to half the width of a three strand rope.

Old floorboards

photo copyright Karin Corbin 2009
There is some parallax in the photo above from my older digital camera that did not have correction for that. The boards are actually straight without curve to them.

I did say this was going to be an old, rustic, coastal cottage. I think a fisherman lives in it. Not sure if he has a wife.

What a worn and somewhat grungy floor. It takes at least 4 times more work to make this kind of floor than to make a pretty, nicely stained and laid floor with no wear and tear.

Every board had to be hand planed to make them look hand cut and also to make them uneven as if there were a little warping going on. I needed to create small gaps here and there between my nice straight boards. Then scratches were added and a few dings of course. There are the hand shaped trenails pegging the boards down.

The finish is done with many layers of stains, golden oak first then pickled oak and on the top layer I brushed in some dark walnut. It is done with a wet in wet glazing method. Then I rubbed down the floor with rottenstone which helps reduce gloss and adds an authentic ground in dirty look. Top with a final pickled oak wash.

If you ever need to put piles of dusty grey dirt into a miniature scene such as an old shed or basement just grab a box of rottenstone from the hardware store. No bugs or critters in it to worry about. Just good clean dirt, actually it is limestone that has turned into powder and surprisingly it is used to polish things.

That worn old floor started life as lovely Sitka Spruce planks meant to be used for the backs and tops of guitars. They were factory seconds that had been tossed in the firewood pile. I have quite a big stash of this wood, love it because the grain is so tight. In the photo below you see some of the floor board strips and also a plank below them that has not yet been cut. The floor board strips in the photo are just under 3/4" wide. If you enlarge the photo you can see the amazingly tight growth rings in the board, perfect for making miniatures.

Brickology Part 4

photo copyright Karin Corbin 2009
Would you look at those miniature bricks in the photo above! WOW I am so thrilled, I actually managed to achieve the look I was after. No way would anyone think these started out as a package of terra cotta, colored paper mache clay, the Plus brand from Activa, from the local hobby shop. They might even think they are real bricks. A few hundred more bricks and I will get to be an expert at making the chipped edges. Right now the chips are too similar looking. Picky, picky I am so particular I will drive myself nuts. You can't see the difference without a 10 megapixel camera aimed in as a magnifier.

So today it is time to describe how to take the bricks you made in the previous tutorial segment, using the food processor, and cut out on the board and get them to look even more realistic.

The first step is to take your scalpel and clean off any rough edges from the cutting process. Then take the scalpel and make some chips in the edges of the brick. You can chip off a corner by putting the knife against the side edge and pushing it in a bit while pulling up towards the top of the brick. A lot of the bricks are not truly straight edge so you can create a little curve by carving away some of the edge of the brick. If you want to round over the edge to soften a few here and there use some fine sandpaper. Also you might want to add a few more voids and chips into the top surface of the brick. The scalpel is also the tool for that as are fingernails.

So that is it, sandpaper, scalpel and fingernails to refine the shapes and the most important thing is to have good reference photos of real bricks. Don't go looking at my miniature bricks when you make yours or you will be making a copy of a copy and they won't look nearly as realistic as they could.

You have started out with a batch of miniature bricks that was a fairly uniform color. The color change is done with good quality water colors. You will need black, raw siena, burnt siena, yellow ochre, and white. If I had some blue on hand I would have used it to modify the black here and there, some of the burnt areas on the real bricks had a blue and purple cast to them. Next time I head to the art supply store I will pick up a tube of blue.

Looking at photos of real bricks try to copy as best you can the color variations. Water colors will blend into each other and soften the edges of color bands and that is fine. Don't forget to carry the watercolor down onto the side edges of the brick. You don't know if the grout will completely cover that edge or not. Hopefully some of your bricks are of slightly different thickness or even warped a little. On a real wall bricks are not perfectly laid with absolutely flush surfaces or even in perfectly level rows and spacing. Slight variations in your project are essential, cartoon like giant, variations will make the project look clumsy.

Next you will need to seal the bricks to keep the colors from running when you grout the wall. I have used a stone sealer on mine, it adds no gloss to my miniature bricks. The sealer I used is by Aqua Mix, Sealer's Choice 15 gold. I purchased it at either Home Depot or Lowes, sorry I don't remember which store it was. This is a water thin liquid in a bottle, you can brush it on or even air brush it on.

I have detail carved, painted and sealed my bricks as individual pieces held in hand so I had something to show you on the blog. Normally though I would first glue the bricks to the dollhouse surface and then do those tasks. It is also much faster to do these tasks when the bricks are installed than trying to hold, pick up and put down individual pieces. This method is slow enough without that!

Brickology Part 3



This Brickology lesson is for making handmade, antique style, miniature sized bricks using paper mache/clay air drying products.

The clay I am using today is Plus by Activa, their Acitv Clay formula works too. I have tried the Das brand of clay but did not like the results, it has too many paper fibers to give a clean cut. All of these clays are made from earth minerals which are the clay part and for strength they add paper fibers along with a few other ingrediants. I started with a terra cotta colored formula. If you let this product dry it won't look like terracotta, it will be a pale pink which is sad because it means more work to get the right look.

Right out of the package the Activa Plus clay is too wet to roll out with a pasta roller. If you simply take it out of the packackage and immediately roll it out with a rolling pin the surface will be very smooth and that won't look like hand made brick. So I started messing around with the clay to see if I could dry them out, improve the color and achieve the textures of hand made bricks.

The idea for the ability to make the  clay behave differently and get a different surface texture on it is based on my experiences of making the perfect pie crust. The idea there is to create crumbs and then add just enough moisture to get it to stick together. The dough has to be handled gently so you keep the crumbs, which are fat coated with flour, intact enough to create flaky layers. Too much water and it turns to mush, too little and guess what the crust is not smooth it cracks and flakes. So that is how I approached making bricks that have texture with cracks. But I will tell you up front that getting the mix just right can be frustrating and there is a learning curve to it.

I do the mixing in a small food processor. I tried it in a full sized machine and it did not work for this method, too much volume to get the clay to crumb. I got a very nice small Kitchen Aide machine that was on sale for $30.00. You don't need a high powered machine. The only speed button this machine has is for pulse.

Because the clay is too wet to start with you need to do something to dry it out. You could pinch it into lots of little pieces and let them stand for a while to evaporate some of the moisture. I added in some powdered earth pigment which soaked up the excess liquid. I also added in some PVA glue for extra strength. Adding more PVA helps moisten the clay if you get too dry of a mix. The ingredient I added to increase the strength of the color is tinting medium which I purchase at a local paint store by the ounce. I put in a terracotta color. Even with the added color the bricks will dry too light but you can paint on toning colors after they dry.

I make up lots of smaller sized batches. If I get a batch that is too dry or too wet I set some of it aside in a lidded storage container. Those not quite right batches can be used to adjust other batches that don't have the right moisture content. Also you start to get many color variations which is perfect for a hand made brick wall.

In the photo below the clay mache has had powerded earth pigment, glue and tinting medium added to it. It is nicely crumbed but it is too dry to roll into bricks. I do try to get my mix to this stage as it is easy to add more moisture to get it to begin clumping. Be sure to set aside in a covered container some of these too dry crumbs in case you need to adjust a mix that becomes too wet.

The photo below shows a batch that is just about right, a little more moisture is OK but not any more dry than this image shows. To the crumbs I have now added more PVA glue and also some water. Adding glue only will make the clay much too sticky to go through the rollers, it needs to be a little slick to pass through. You can tell you are at the right stage because the crumbs start to clump together, just like that pie crust making method. A perfect mix is the instant when the clay suddenly becomes a ball but it is easy to make it too wet so I stopped just before that point. A spray bottle of water is an easy way to add just a little bit of water without going too far. So it is pulse, check to see if it clumps, if not then spray some water, check again and keep going until the mix starts to bond together. My mix turned out to be a little too dry for perfection but it still worked out OK.

Now that you hope you have a workable mix you need to see if it will go through a pasta rolling machine. I am using an Atlas machine I found at a thrift shop. You can now purchase these pasta rollers for using with Fimo type clays. As seen in the two photos below first make a clay burger patty.

Now cover the patty with a piece of flexible cutting mat and take it down to about 1/4 inch or so in thickness. That will allow you to run it through the pasta machine. I am using the #3 setting on my machine. How thick you want to make your bricks is your choice, there is no rule to this game. All that matters is getting the look you want for your miniature building.

Now run the clay sheet through the pasta rollers. The sheet should just hold together. If it does not hold together and come out as a sheet because it is too dry put it back in the food processor and add more water. If it is too wet and sticks to the rollers then put it back in the food processor and mix in some of the reserved dry crumbs. The rolled clay sheet might come out pretty rough looking and it might even have long pieces flaking off the surface (or it might look perfect). Both those factors are great, you want this, you don't want a perfectly smooth surface. Mine came out pretty darned rough with a few holes, I was in doubt it would be good enough to use. Look at the photo below,I catch the dough as it comes out on that extra piece of flexible cutting board.

In the photo below I have just trimmed off the dough into a rough rectangle and I have patched up the holes. Then I slid the clay dough onto my cutting board placing the flex mat on top for the next step.

Take the rolling pin and using it over the top of the flexible mat smooth out some of that rough texture that came out of the pasta roller. Your piece should look something like the photo below. Maybe it has more cracks and rough spots, maybe it is smoother. The point of making small batches is that you will need a lot of variations in textures to make a good looking brick wall. No two batches will roll out the same and that is good.
My friend Don noticed something in my finished brick samples. There was a trend for the details to run from right to left on the same direction of diagonal. Don has an incredible eye for detail, I sure did not pick up on it. This was caused because I always rolled the pin from right to left on a slight diagonal; be sure to vary the direction you do the final, smoothing with the rolling pin on each of your small batches so you get random details on the surface of your bricks.

Now things get much easier, all you have to do is make the cut lines. You need very thin blades for this, thick blades mess up the edges. So there are two tools of choice a scalpel and one of the very thin, long razor blades made for slicing Fimo type clays. The scalpel works good for the long lines and the blade is good for the short cross cuts. I find using the scalpel for the second cut leaves little pulled out of shape hooks of clay. Those can be trimmed off later if all you have is a scalpel. I tried using the long blade for the long cuts and it is hard to get it to line up if not long enough for a row. I am using a steel ruler and lining it up with the marks on the grid sheet under the cutting mat. My ruler was cork backed so I put the cork side up to keep it out of the sticky clay. Steel washes better than cork. Take any leftover scraps from around the edges and toss them back into your covered container of mix, you can add them into the next batch.

Now let your bricks dry. If I place my boards in front of a fan the air movement dries the bricks to leather hard in 10 to 15 minutes. I can then transfer them onto a baking sheet and finish the drying job in a few more minutes at low temperature, 150 degrees in my convection oven. But that is the hurry up way, you can be green and let them dry for a day or so. The sun makes a great, quick energy source for drying but that is in limited supply at the moment. If the bricks start to warp cover them with another cutting board, flex mat side down or the spare sheet of flex mat and a magazine. Let them breath once in a while to evaporate the moisture off.

The next part of the lesson will be cleaning up the bricks, adding more texture and painting them. The long tutorial is almost over!

Brickology Part 2

This Brickology tutorial segment is about making the cutting boards you will be needing. While each brick will be unique there still has to be a way to control the size of the brick.

Knowing what era your dollhouse was built or remodeled is the first step in making bricks for the project. I can't tell you what size to make your bricks because depending on the date, the geographical location and sometimes the architect the standard sizes of bricks varied. During Queen Elizabeth's rein the size standard was different than the size during the rein of Charles I. These sizes were controlled by laws. Early American bricks were influenced by the British standards as the brick makers were immigrants. The modern standards in place now are created by builders associations. Tax rates were also an influence, structures might have had a per brick tax, that meant the bricks got larger so the tax would be smaller. While that brick tax was going on in England there were some really large brick sizes used on new buildings.

So do your research and find out what size the real life brick would be and then divide 12 if you are making a 1:12 project. Don't worry about rounding up to the nearest fraction, the decimal answer is better to use. The next step is to cut a brick to that dimension and find out how much it is going to shrink. Yes these clay materials always shrink so you must increase the size of your miniature brick pattern to compensate. You will only find out by experimenting what dimension you have to start with. As there is more material lengthwise in a brick it will shrink more in that dimension. Next use a program that will allow you to duplicate lines across the printed page. That creates your cutting guide.

You will need to make layout pages for the lengthwise bricks and if you want to also make them for the header courses of bricks. Header courses are where the length of the brick goes back into the wall instead of across the face. This provides greater strength for walls. So this is yet another wall detail you need to decide on, are you going to have header courses and how often will they occur? Some brick wall patterns have a lot of headers in them. There might also be decorative soldier courses. You will also see these long edges of the brick exposed in arches over windows and doors. Just running bricks lengthwise over these opening is not architecturally correct. Those are load bearing areas on a real building, the wall above the door or window would collapse into the opening if they are not properly engineered. Don't forget window sills, they too have a special pattern. Search out images and web pages that show how to build brick walls. Look closely at photos of real brick buildings from the era of your dollhouse.

Because this is a small batch method of brick making due to the width of the pasta roller machine I have made a number of cutting boards. My boards are made using some leftover plywood, I could have used pieces of melamine coated bookshelves. I adhere my guide lines to the board with 3M Super 77 spray adhesive. Next I put on the top surface also using the spray adhesive. That surface is a clear, flexible plastic cutting mat. You can find these at grocery stores or in the kitchen section of a department store, hardware store or kitchen store. I got the big ones and cut them in half. They came two per pack so that made 3 project boards. Only 3 because you will also need a piece of cutting mat that is not attached to a board. I will show you why you need it in another segment of the tutorial.

If you buy two packs you can create more cutting boards with a different grid size on the backside of the brick cutting board. I have a roof tile grid on one side of my board and a brick grid on the other side. I also have a long brick grid on one side and the header brick size on the other side of the board.

The cutting board is also the drying board.

1st sample real clay brick

I just rolled out and cut my first trial sample from the real clay I purchased. After they dry I will fire them in the kiln. I want to make several batches in different thickness to see what works best. Some bricks will be thin to use as a brick veneer over the plywood or other dollhouse shell materials, others will be 1:12 scale full dimensioned bricks. I also want to try making veneer corner bricks.

I loved working with this regular clay a lot more than I did working with the Das, Plus and other brands of clay/paper-mache mixes. It cuts nicer and the color is much better. The variation in color you see in the photo above is that some of the bricks are close to being dry as they were near the halogen lamp and other bricks are still pretty wet. The clay is not a bad bargain at $10.00 for 20 pounds. Of course the real expense is in the firing and the cost of the labor. But cost aside I can't purchase this product and there are no tutorials on it so I am teaching myself the skill.

So far I feel I am on a good track towards achieving a realistic texture to match that of old handmade bricks. There are definitely a few tricks up my sleeve that makes that texture happen but nothing too complex.

Brickology Part 1

photo copyright Karin Corbin 2009


Today I started walking the immediate neighborhood taking photos of bricks on old buildings. I started making miniature bricks last night. My new dollhouse has a raised hearth fireplace, wood storage underneath, built in spice cupboard to the side. I have not gotten as much of the construction done as I hoped as I had to design the fireplace. It is not looking promising to make a 30 day completion goal but I am having a lot of fun so I don't really mind. There is a Seattle dollhouse show in March.

My roof tile method is what I will be using to make the brickwork on the hearth. This blog is a bit of a teaser in that it only contains reference photos of bricks that I took at lunch today. The how-to blog is coming later when I have the hearth finished and ready to photograph.

I am going out on a limb here and state my opinion that egg cartons do not make realistic looking bricks on dollhouses. The closest it comes to reality is where the hard kiln fired face of a brick has broken off and the soft clay inside is eroding away. Mushy rounded over edges on paperclay bricks don't work either.

Having stated that strong opinion I will soften it by saying that not all dollhouses have to be photo realistic looking, they are fun and they are a form of folk art where photo realism is not the point. The dollhouses I create are a blend of folk art and realism. So you keep right on doing what you love best because it is good and great. But if you want to try for something closer to the real thing then go and look at the real thing, look very closely, touch it, feel the surfaces, absorb the experience into your memory banks. Use a camera and record the experience to take back to your studio. Pick up a fallen brick from an old wall to use as a door stop or to weigh down something being glued together.

The photos that follow are the record I made of a late 1800's structure in the neighborhood that was built with local, hand made bricks. The color variations come from the position the bricks were stacked in the kiln. The smoke and heat creates a kind of glaze. Some of the striped color variations are from where an adjacent brick was stacked thus protecting the brick from the heat in that spot. Heat also creates cracks and spalling. Because the clay is hand packed into the molds there are often fissures in the layers of clay. The clay itself has grit and other inclusions in it and there are variation in color from the earth. When the mold is removed from the wet clay it can distort the shape of the brick. Moving the newly formed clay to the drying shelf can distort it and the person moving it might leave visible prints of their fingers. while the bricks are of similar size and the clay material is dug from the same pit there are absolutely no identical bricks unlike modern manufactured brick where they all look the same.

These brick photos do create a kind of abstract art where you look at things in detail. Don thinks I should do a gallery show of the images at a local coffee shop and sell people the prints. Who knows maybe I will give it a try sometime. I will need to shoot at the golden hour of intense sunlight from the west when there are long shadows.
