GameCraft Miniatures have introduced a simple laser-cut felt road system, both in "paved" (black) and "dirt" (brown) varieties. The laser cutting actually prevents fraying, which is a reasons to buy this product instead of just making your own. I dont feel that felt usually lies down flat and trouble free, but this might be an exception. Regardless, its worth a look. Speaking of looks, here is GameCraft doing a short video presentation on it!
