I watched this video yesterday and today made a couple pinwheel blocks to try out the method. Originally I thought the method was interesting, but probably time consuming. I was way wrong! This is a fantastic way to make a perfect pinwheel block. Once sewn, and turned to the back....."swirling center" was already in place...no need to swirl it yourself. Also, the seams were going in the direction needed for pressing...no guess work! I will never make a pinwheel any other way again! Thanks so much for sharing this video!
