Most recently, I created a couple of forest terrain pieces. A friend is borrowing them at the moment or I'd take a pic, but it's basically a piece of styrene plastic sheet cut to an irregular shape about 8" across. Then, I took some model railroad trees and glued the bases down. These trees detach at the base which is useful for storage and when a large model is moving through the woods I can take the trees out of the way.
Then, for the bare trees that have lost their leaves I glued some railroad scenery autumn leaves to the ground around the tree.
Finally, I spray painted the sheet with natural forest floor looking colors.
Works decently well.
