I only use the Wonder Clips when finishing binding by machine. I put them fairly close together and they held everything perfectly in place. Using them I was able to satisfactorily straight stitch on a binding the first time I used them. I tend to be a perfectionist and was totally unhappy with my machine finished attempt before. I finally resorted to a decorative stitch. Not my first choice. My real preference is hand finished and I love to do it. There just isn't always time.
