DH bought me a quilt rack years ago from a company called Robinson's Woodcrafts. I don't see the one I have for sale now but there is a picture of it in the photos section of the website. Mine holds 4 quilts & the picture shows a one quilt rack. I really love it & it's easy to put on & remove my quilts. That wooden bar that the quilt hangs on slides into slots on each side. There is a notch cut on on the bottom of each wooden bar so it won't slide off while your quilt is on it. I think your brother could make something like this. Mine is 38" wide & 24" high & holds 4 quilts.
