Wool
Wool can be spun or made into yarn. Wool is usually carded before it is spun. Carding is a way of making the wool straighter, using two brushes. The yarn is used to weave fabric or material.  The yarn of wool can also be knitted or crocheted into fabric or clothing like jumpers. Alpaca, mohair, angora, camel, cashmere and vicuna are all separate types of wool.
