I sold hundreds of boutique-size tissue box covers when I did shows. People were looking for either "themed" fabrics like dog breeds, cats, hobbies or sports, coca cola, John Deere, even pigs, anything that people collect, or seasonal prints so they can accent their tissue boxes all year round. Don't forget the kids prints or fabric for men. Also, try to have a variety of price ranges. The $50.00 table runner may be beautiful, but the gift exchanges people are in, have lower price limits as well as people with limited incomes that just want a small "thank you" gift for someone that they want to remembver. Small gift card envelopes use up little scraps of fabric and make great stocking stuffers. If you crochet or knit, cotton dishcloths are always a good seller.
