I’m starting a small 2’x2’ layout with one loop, N scale, for a small Christmas tree to sit on. I have a Durango steam engine so I’m going to get a cabin to build, some trees, etc.. I’m also going to put some ballast down. But undecided on mat vs paint for the foam base. The mat seems easiest but not the “realist”. But painting I guess I’d have to put some grass down too? Thoughts? Opinions?
