If you're interested in making some for yourself, I used heavy duty scotch brite brand scouring pads that I purchased at the big box home improvement store. Two packages ran me about $4.00 total. The spray paint and blended turf flocking I had on hand in my shop, but I would guess I only used a few dollars worth of each. Pretty good deal to get all this terrain for under ten bucks and a couple hours of work.
