if you are workin on a board bow, keep it wide and it definately wouldnt hurt to back it, anything fairly tuff will work. I actually backed one of my earlier bows with denim from an old pair of pants. And on a few i backed with some mossy oak camo that i cut off the slieve of an unused garage sail purchase

,the latter turned out looking pretty good and serves fairly well covering up that bright orange if you are gonna be huntin with them. Ty
