I bought some cheap, porcelain houses and thought they might make good terrain for my games.
They were originally white and then I sprayed them down with black primer. Now I'm going to use another rattle can spray for the base coat.
Here is the spray paint I used for the walls. Yes, I know the picture is awful but you get the idea.
This after I sprayed the houses. My oldest son, Mr. A, provided all the help he could being three years old (which is limited to moral support at the moment).
