What is Felt?
Simply put, felt is matted wool. Wool becomes felt when it is subjected to moisture, heat, and pressure. Hot soapy water makes the wool slippery, and causes the fiber scales to “open up”. The scales prevent the fibers from backing up again after they slide across each other; with agitation, the fibers get hopelessly tangled together. When cooled and dried, the scales close and lock the wool into the tough, durable material called felt.
