I bought a cheap wire grid rack for displaying. It worked out great , I can use cloths pins to attach. It stands 6 feet tall giving great height and improves what is visable to the customers as they pass by. I did the cloths rack thing ... poor sales ... used the grid .. sales went up 400 percent.
Or look for a used architectural drawing hanging file. They are similiar to the rug hanging things. Many architectural firms are discarding their hanging files since so much is stored electronically. They have a continuous clamp along the top and hold about 15 drawing sets. You can double up ( back to back ) the quilts and get 30 on some these type. They can be pricey new ... but if you can find one used they go for really cheap.
this is a photo of what I am refering
