I've been making my own since in s/s school in early 80s. Best way is to use mesh for overlayer and to tie/sew on. Use jute,burlap,and camo cloth to make shapes,leaves,and uneven forms,tie/sew on. Word od thought,you want to keep pards of it "open" to shoot bow without ripping it off and causing miss. Cleaeance is the word I was looking for. You don't havta go overboard as this'll breakup your outline nicely anyway.
