Wool is a natural fibre, obtained from several animals. To qualify as wool, rather than hair, it should be fine and have a crinkly appearance.

Wool usually comes from sheep or (angora) goats. The fineness of the fibre (down to <10 microns) and its crinkle are the most valued. The inner coat of a dog, in winter is quite wooly, but less so for cats.

Similar fibre is obtained from Alpacas, and Vicuna (the finest). Once these various fibres have been cleaned, they will last for very many years.

Wool may be spun into a longer fibre, dyed, woven, and felted.
