I cut mine 9 inches, fold and stitch a tube. finish ends too. then I always hand stitch just under the binding, then take the tube/sleeve and fold up to just under the top edge of the quilt and flatten out the sleeve and pin the bottom where it lays and hand stitch that down. the "extra" you got from the little folding will help the hanger you insert not pull on the quilt. all should hand well. I think I remembered to machine stitch the sleeve on one quilt. I always think of it too late.
