i may depend on how you do your binding. I do my binding by machine. I stitch the binding to the front of the quilt first then turn it to the back. But to stitch down the back side, I again do this from the front of the quilt, so I can make sure my stitching lands in the binding ditch. this means I cannot see on the back to confirm if i am "catching" my binding. I used to pin, which wasn't too effective. Then I tried glueing, which was very effective but time consuming. I have recently tried the clips and they seem to be a happy compromise. not as precise as glueing, but soooo much quicker than both. so if its not a show quilt (have never done one and unlikely ever to do one!), then the clips work good enough for me!
