Make an “exclusive” design for each specialty shop. They will promote their very own exclusive design. This would not apply to consignment or gift shops. For example, I do my apple stopper for a local winery that is in the middle of 100 acres of apple orchards. I told them I would not sell that design to another winery within 50 miles. If you have 4, or even 15, wineries within 100 miles, that is a nice number of “exclusive” designs to sell.
