I bought 10 with a 40% off coupon from Hobby Lobby. I was not too impressed. Later, I saw 100 at a 50% discount. I bought them and now I cannot imagine putting a binding on a quilt without them. In fact, I like them so much that I am looking for 50 more at a good discount. I like to clip all of my binding at once and I need more than 110 on a king size quilt. I know, I do put them fairly close together. I think that the reason I did not like my first 10 was that I was constantly repositioning them along the binding.
