I saw somewhere where a guy substituted floral foam for Woodland Scenics ground cover… Look how it turned out! Just take a block of that green floral form from your wife’s stash, or get some from the crafts department of your favorite discount store. Take a cheese shredder (I got one at the Goodwill) and using short strokes, (Experiment a bit) shred it to bits. Look at how this turned out! I think it’s better than the hobby shop stuff!
