Felt is a remarkable fabric, created without the use of stitching, weaving, or knitting. Instead, felt is fabricated by the interlocking of fibers through a combination of mechanical work, chemical action, moisture, and heat. Felt may consist of one or more classes of fibers, wool, reprocessed wool, and reused wool, with or without admixture with animal, vegetable, and synthetic fibers.
