These clips are fantastic! Love the rainbow look and the ability to slide the clip off the fabric while sewing, unlike the wonder-type clips that require me to stop sewing each time I come up to the clip. I have a pretty big cup of wonder-type clips that I use on thicker material (these clips don't have the strong grab that the wonder-type clips have for that application). I started out with the larger "hair" clips I bought at Sally's Beauty supply, and while I still use those clips on bigger sections, I love that these work well for smaller areas that need to be clipped. I have just decided that I will add a 10-pack to each order until I have enough (who knows when that will be though. lol)
