Wool is a natural fiber obtained from the fleece of sheep and other animals, such as goats (cashmere and mohair) and alpacas. It is known for its warmth, durability, and moisture-wicking properties, making it a popular choice for clothing, blankets, and carpets. The process of obtaining wool involves shearing the sheep, cleaning the fleece, and then spinning it into yarn. Wool can be processed in various ways to create different textures and qualities, such as merino wool, which is soft and fine, or lambswool, which comes from the first shearing of a lamb.
