Either a ladder or more traditional quilt rack would work great. It all depends on how many quilts you want to display/hang, the amount of space you have for a rack, what goes with your decor, etc. I have a quilt rack in my bedroom and the very first quilt I ever made is hanging on it. I have several friends with different kinds of ladders. I have always liked the way they look and have an order for one in with my husband--if he EVER gets his wood shop finished!!!
PS--I want to see pics of your custom sewing center, too!!!
