I was thinking about how to texture the walls and remembered these:
Mikey picked up about a dozen jars many years ago for about 50 cents each and gave me a couple. After all this time the paint is still good so I slathered on the pink paint with abandon. It even has glitter in it. But not to worry, after a coating of brown latex you won't be able to tell.
Four buildings assembled and textured. The roof sections are reinforced with popsicle sticks to prevent warping.
I've used most of the pot of paint. But it goes on thick so I've been able to cover the edges of the foam core without the step of applying caulk or putty first.
