Ive made them for a few years, but I havent had as much success as I thought I might, but it has worked for a couple sheds. I drive 2 or 3 fence posts about 18 inches or 2 feet apart, sometimes in a W shape or V. Then I stretch a couple rubber bungee cords between the posts. I dont stretch them real tight, just where they arent hanging loose.Then pour a little corn under it. If a buck isnt ready to lose his horns, and they get caught in the straps, it just pops the strap loose, and hes free. The straps will come off the post, or break with a good pull, but if the antler is loose, it will come off. I think the deer dont like the smell of the rubber or something. I have even put the post out early so they are used to them, but when the bungees are put on, the deer dont come to it nearly as often.
