It would be better to use the heaviest possibly a 1 inch piece of pvc. The black pvc used for piping would be ideal. I used 3/4 inch schedule 30 pvc. I live in Southern Nevada and we don't get extremely cold weather, where I would have have to worry about the pvc cracking. It does drop into the low 30's but I had to also deal with transporting considerations. This was the way I could fit the blind into the ski bag. You also have to be worried about 1/2 in. Pipe being to flimsy. Also you have to build it where the major support is all glued together so all you have to do is connect the support pipe together and wrap it with the camo netting and clip it in place. You can build the blind to the dimensions to suit your needs. If I were to build another one I would have made it a foot longer, but then again I am faced with transporting it, and finding a way to systematically setting it up in darkness and tearing it down in a short time frame and finding a bag that will hold it. It's not perfect but it works. If this is something I find myself using a lot, I may go with an avian (600.00 bucks). But I can't see spending that kind of money on something I may use once or twice a season. So if I'm out $$$$, it's about 60.00 tops for the material and my time.
