I'm placing some structures on my layout and there's occasionally an unsightly gap between the bottom edge of the structure and the surface where the building isn't square. I was thinking of adding a little line of coarse grass to cover it up or maybe putting some scale junk in front of it.
Any other suggestions?
PS: Any helpful suggestions for insuring that my future structures are square? I was thinking of cutting a wooden block that matches the internal dimensions and building on a flat surface, but that seems too cumbersome.
