Dont know what kind of area you will be hunting but in the past I have taken large pieces of cardboard, cut to a hight that I needed., covered them in a spray on glue and cut tall sage brush and grasses from the area I was hunting in and covered it. Take a few stakes, used rebar and wood both, poke holes in the sides and wire it to the stakes. Left one standing in a feild for 3 months. Worked good. Just get inside, I had a chair I kept in it.
