Feltnjön
Feltnjön is a term of uncertain origin, but it is commonly understood to refer to a type of hardy, felt-like material. Historically, it has been associated with traditional crafts and utilitarian purposes. The exact composition can vary, but it typically involves matted fibers, often wool or similar animal hair, which are then processed to create a dense and durable fabric. This felting process involves interlocking the fibers through mechanical action, moisture, and heat, eliminating the need for weaving or knitting.
Feltnjön has found applications in various cultures for items such as footwear, insulation, and protective coverings.
