If you’ve ever seen or felt the coat of a sheep, you may be surprised to learn that the coarse, dirty hair that protects these creatures is the same material that your wool blanket is made out of. Wool is a great fabric for clothing and blankets because it naturally regulates temperature, making it the perfect coat for sheep in the wild and human beings in their homes in many different climates.
Wool is a natural fiber that breathes in hot weather and insulates in cold. The wool your blanket is made of is generally called apparel wool. This means it is of a high enough quality to be used to make blankets and clothing. Wool is also flame-resistant, making it a safe material.
