OK, I watched the Youtube, and thought how easy it looks - and it was, for the first 3 feet or so. Then the wind knots hit(threw it away). So I watched it again and stretched it first, then kept the "legs" apart so they only knotted on themselves and not each other - made that one about 4 feet before I threw it away. Threw one more away before I finally worked harder at keeping the legs a little tighter and was able to make about 6 feet, but easy it's not. Anybody make these and have any hints?
