There is a U tube by the American Quilt Society explaining how to make a hanging sleeve. There are other Utube videos also. I followed the AQS video when I made a sleeve for my first quilt I displayed. It is really easy. Most sleeves are muslin. One of the Utube videos showed using the same fabric as the backing and I don't see anything wrong with that. The AQS video is the accepted sleeve for entering a quilt show.
