I found this tutorial on building a miniature building and a companion article on painting. The intended audience is wargaming, but the same tricks work for buildings for train layouts, or for kids to build cities for their Matchbox/Hot Wheels-brand cars or their action figures.To me, the gem was the technique on painting windows. I have never figured out how to draw or paint a glare on a window that looked the least bit convincing.

The most convincing way to get a glare or reflection on a window is to cut out the window, cut a piece of slide glass–or, in a pinch, plastic packaging–and glue it into the window. Or if you’re not going to detail the interior of the building, cut a piece from a gallon milk jug. Nothing looks more like a window than a window.

But for those times when that’s impractical, or for those times when you want a bit more of a toy look, the technique in this article is exactly what you need.

Don’t discount this as a fun craft for kids. Kids get bored easily, but this allows them to use their creativity, and it teaches them hand-eye coordination, problem solving, and it’s the only fun and interesting application of math I’ve ever found. If a child is struggling with division, like I did, here’s a motivation.

How do you turn this into a math lesson? Instead of eyeballing the size, encourage the child to figure out how big the building ought to be. If the building is intended for die-cast cars, measure a toy car. Then measure a real car. You now have a ratio. (Most die-cast cars scale out to somewhere between 1:64 and 1:76 scale). So, figuring that a one-story house is about 12 feet tall, multiply that by your ratio to figure out how big a floor should be. Measure doors and windows and multiply that by the ratio to figure out how big those should be.

The result will be toys that look better because some thought went into their proportions, and your kids might learn to enjoy math a little bit. I know I would have paid a lot more attention in math class if I’d realized I could use it to make cool toys.

At some point you might want to head down to Radio Shack to pick up some miniature light bulbs and teach your kids a little science lesson too. Horror of horrors, they might find they like that too.

Or, if your child is very inclined towards math and science, and hates art class, this might be a way to give them a bit more appeciation of what they learn in those classes.
