hanging a real quilt for any length of time is never a good thing...the weight alone will eventually put stress/strain on the seams. the binding can not withstand years of hanging from clips either unless you are able to rotate it every few months so it wears evenly.
I have wooden hangers that have a slot for the binding to fit into and then the front screws down on the quilt. But I only hand smaller wall type quilts, not a huge queen or anything that heavy!
