It's unclear to me exactly what you're asking our help for? You want to know how to contact the organizers of the Quilt Festival? There are several, located in Salt Lake City, Atlanta, Long Beach CA, Houston.... You can search for the quilt festival in the town that you want, and the website for that festival will have contact information.
If you want to sell your book at the festival, you will need to apply for vendor credentials and rent a booth.
