I've been using my daughter's left over hair clips with bright colors on them. I love them and they are fun in the bright colors but some people have said the ones you buy specifically for quilts are different. How can they be different and what is the difference? I have seen some larger ones in the quilting supplies. They would have worked great on the flannel quilt with warm and natural batting I just made. It was just a little thicker than the cotton ones I usually make and the regular hair clips didn't do the best job.
