A while ago I made a rough plan for a little 4x6 Marx layout to show off a bunch of the accessories I have and to use my Marx stuff on instead of my postwar Lionel layout. I never got it built but I'm thinking of going for it now. I'm torn on what to use for the ground cover. I don't want to just paint the OSB plywood I have for it because I don't think it would cover well. It'll be all tinplate and I want something to maintain the feel of the trains. What works well?
