Wool is the natural fiber grown from sheep. This means wool is flame-resistant . Different breeds of sheep grow different kinds of wool.
Sheep can grow fine wool, medium wool or coarse wool.
Fine wool is often used to make suits . Medium wool is often used to make blankets . Coarse wool is often used to make carpets . Sheep have their wool removed in one piece called a fleece. The fleece is washed in big tubs to remove dirt, grease and grass.
