I've been wanting to build a hay bale blind for quite a while, and thought it would be a good first project in my new shop. There were plenty of things I would NOT do again, so thought I'd share. Hopefully, you find it useful. A couple treated 8ft 2x4's were purchased and cut in half. A few 2x6 scraps were cut at an angle and deck screwed in the corners for a little strength. I had a couple old hog panels laying around, so those were utilized as the outside of the blind. They started out at 16.5x4.5 feet. Three squares were cut off the length (about 2 feet) to get the size about right (eyeballed). A 14 ft panel should work great. The hog panel was bent into shape and wired temporarily to the frame. The hog panel was then attached with some large fence staples. This worked okay, but not great. Adel clamps would be better or maybe some small electrical conduit clamps? Just the wire would probably be enough.
