I attach my hanging sleeve right under the binding. As a matter of fact, I baste it on, raw edge of sleeve matching raw edge of wall hanging, then the sleeve gets sewn on to the wall hanging as I sew on the binding. The binding is then hand sewn on. Once completed, I pin the sleeve down so it doesn't move as I whip stitch the bottom of the sleeve onto the wall hanging Maybe you could get it back and sew on a new sleeve on the top of the wall hanging's back.
