I have the binding kit-have used it a couple of times. Personally, I don't think it's worth what I paid for it. It comes with a tutorial DVD, but the lady talks so fast, I have to keep starting and stopping it to keep up. The main thing about the system is you use binding clips to clip your binding down before you sew it and there is a choice of 3 mitre clips to use at the corners so you can get a perfect corner everytime. It's basically the same way to attach a binding a that we've always used, you just use these "gadgets" to do it with. I'm working on a lap throw now, and the clips won't work because of the thickness.
