I use an old ladder that was my grandfather's. It's got 9 rungs and holds quite a few quilts; I also have a bunk bed ladder (found it on my neighbor's trash heap) that holds small quilts and table runners. I like the idea of a metal rack that hangs-thanks for posting this.
(Just remember when using a wooden item cover the rungs so your fabric isn't in direct contact with wood; this shouldn't be a problem with the metal one.)
