I purchased the wonder clips awhile back and tried them while sewing on my binding. My thread kept getting caught on them so I went back to using straight pins. While working on my log cabin quilt binding, I decided to try them again. This time I didn't have any problems. Don't know what I was doing differently last time but I'm using them from now on. I still pin at the miter corners but everywhere else I use the clips. I have 150 and sometimes that's not enough if I have a couple quilts waiting to be hand sewn. Anyway, I love them and though they may be a little pricey, they're worth it. I think I waited till I found them on sale before I picked up 3-50 packs.
