I am going to construct a homemade blind out of EMT. I was thinking about going with the millitary camo netting on the outside, but want/need some sort of backing material, so that I can roll the material up without that crap hanging on everything. I thought about sailcloth, but I can't seem to find anything like it, and brulap (might hold too much water?). What are yuor suggestions as to what to use for a backer-windproof and water resistance are a definite plus-and where can I find it?
