I think what you're remembering is a simple square "frame" made of four pieces of lumber about a half inch thick and about 3 or 4 inches wide...build the square so that the four sides form a center hole large enough to fit the folded quilt thru. the final hanger will have a solid front/sides/'back, with the half inch edges at the top and bottom of the unit.. if you're into country decorating, I've seen many similar hangars built with hearts attached to the front of the box,,,or a wooden bow, etc. It would be easy for someone to make with limited woodworking tools.
Hope this makes sense.
