I see what you mean about there not being anything under the cover. That's possible. A lot of Pier One's items are made from imported cottons and rayons that are not really good quality. I'm sure that a good quilting cotton will be a lot better than what is on there now. Good luck and be sure and post a picture of the final result for us!
