I can buy leafy wear camo and other patterns from a local tarp/blind, canopy maker for cheap. I get 4 or 6 fiberglass electric fence poles and cut slits int the fabric to slide the poles through it, hot melt glue the top and bottom, and on each end. It rolls up in a 3""x4ft roll,with 2 big rubber bands around it. I sharpen the ends of the poles on a belt sander before assembling. YOu can just unroll, stick in the ground, an adjust you height by pulling the poles closer together and letting the material sag if you want to. I made 3 of these for$35 total. If you want a sling, cut a piece of rope or leather shoe string and tie to each end, throw across your back.
