Felt is a warm, soft, tactile fabric. It can be shaped, steamed and easily manipulated to form all sorts of angles and dimensions. It can be thick and insulating as in a warm winter coat, or it can be light and fluid as in a summer Nuno garment.

Traditional felt has no internal structure. It is not woven or knitted, but is simply a collection of fibres, such as wool, alpaca, rabbit etc, that with the addition of heat, agitation and often water and soap, shrinks to form an interlocked fabric structure.
