They're on sale at Connecting Threads - 40% off, but still pricey. Before I buy one, I'd really like to know if anyone has already tried them. The description says it's 5 powerful magnets held to the wall with adhesive. You provide the metal rod in the quilt sleeve.
The one that hangs sizes up to a king size quilt is $33, regularly $55; for 10 to 20 inch quilt is $10, regularly $35.
