A single-page encyclopedia entry on felting from Rees's Cyclopedia. It describes how hatters turn fur, hair and wool into cloth without spinning or weaving, by bowing the fibers apart, layering them, and working them with moisture and pressure so they twist together. It explains why wool's naturally crooked fibers felt readily, while straight hairs such as beaver and rabbit must be prepared first, and it refers readers to the entries on Fulling and Hat.
