Fiber festivals bring together producers and vendors of mostly animal fibers, such as wool, qiviut, camelid, mohair, and angora. Other fibers include silk, linen, and some synthetic fibers. The festival caters to knitters, spinners, felters, crocheters, and dyers in the United States. Attendees learn and see different materials, techniques, and patterns. Fiber festivals also provide a meeting place for people who otherwise know one another only from Internet lists and blogs.
