The Zip Binding System is great. Had it several years before trying it and after I figured it out sewing on binding is a lot more enjoyable. I don't have to take them off as I sew like you do with the clips. They don't fall off if your binding is smaller that what the hair clips will hold. There are 3 sizes binder clips and I've used them all. I also love the rotary cutters by the same company. I don't know anything about this company but I do like these products. While reading a post about how one quilter is tired of reading the same thing over and over (purple thangy)it was depressing (got over it though) Some people find a topic they like but don't have time to read 28 pages to see if their question has been answered. Reading and responding to the board takes time and patience. The skilled quilter teaching the newbies and the newbies revitalizing the skilled. That's what it's all about.
