Sometimes, I press the edge of the quilt sandwich just before I sew the binding on. Also, if I'm having a problem I zigzag the very outside edge before attaching the binding. I don't have any luck turning and then machine stitching. I don't really mind the hand stitching. Just don't like to sew the binding onto the sandwuch. It sure would be faster to machine stittch it. Hope your hand gets better.
