if you ever think of entering a quilt into a show or contest do not pull you backing over to the front for binding - this is a no no for that kind of thing. I have never used backing as binding. It is not as strong as binding should be. To have a strong binding fold fabric in half and sew onto the front with your machine and then hand stitch onto the back. That is the correct way to do it. But if it is just for you and you do not care and want what is easiest for you do how you wish.
