If you plan on making ground blinds out of them I would set/stand 3 of them up and leave the back wall open for you to enter into the blinds and maybe use the burlap camo material for the back 4th wall for easy entry?You could cover the front 3 walls with the burlap camo material or use Cedar Tree branches?You could also make shooting windows in the middle of the skids if You going to Rifle Hunt out of them.
