I've always pinned. I use the binder clips when I'm spreading out the layers of my quilt. I binder clip the backing to the edge of the table and then spread out the batting and then the top. I only pin on the back thru the binding and into the backing after I've sewn it onto the front. Not thru all layers. I always bury the tip of the pin in the quilt to avoid being stuck. Hasn't happened yet. Knock on wood. Never thought to use the clips to hold the binding on. May give it a try.
