The wool that grows on a sheep is like the hair that grows on your head. It grows the same way and is the protective covering of the sheep against cold weather.

Once a year, usually in the spring when warm weather is ahead and the sheep no longer needs its “protection,” the sheep are given a haircut and all the wool is sheared off. It is usually full of burrs, thorns, and natural oil which is called “lanolin.” It comes off almost whole, like a hide, and is then rolled up and tied with wool twine.
