I considered doing this a couple years ago with the poles from an old tent. After pricing out all of the materials (fabric, thread, etc.) I determined it would not be economical vs. something already available at Cabelas. Unless you get it free or at a discount, camo fabric isn't cheap. I would watch sales or follow some of the suggestions here for making more permanent blinds with natural materials. I ended up buying a climbing stand. Expensive at around $250 but the best piece of hunting equipment I've ever bought; light, portable, comfortable, safe. There are cheaper ones available than I bought. Watch the sales.
