I change my layout every couple of years so I don't want hard Landscaping so I'm going to try this again I had pretty good luck with it on my last test, this is aluminum foil that I spray paint with Rust-Oleum etching primer then I paint with a background color, next I sprinkle the Woodland scenic's ground cover while the paint is wet, ADD lichen , spray with hairspray and then I can roll it and crumble it and then stick to my framework
for more support I will use cardboard
a different idea, yet easy and inexpensive.
