I sew hanging sleeves on most of my quilts after I sew the binding down. The sleeves are tubes about 6 inches wide x 2 inches shorter than the quilt. I place the top of the tube about 1 inch down from the top of the quilt, whip stitch it, then sew the bottom.
I have two quilts that have hung in my office for over 10 years - the backing hasn't ripped yet, and the quilts are queen size.
