I developed a homemade wall blind out of 25' of burlap camo. Roll it up like a bed roll and tie parachute cord around both ends and throw it over your shoulder. For setup it just takes a few small trees or branches out in the woods. I sometimes use arrows and clothes pins too. Check out the two pictures in my turkey hunting photos. Contact me if you want additional info.

They are coming out with more of these pre-made wall blinds similar to mine. They look great and very mobile like mine. I don't think you can go wrong with buying one.
You will be amazed at how much you can get away with from behind the blind. I can hunt pretty relaxed now. My primary reason was for bowhunting but I now use it during the shotgun season.
