Wool comes from the soft fleece of sheep that are sheared (shaved) once a year.
* According to some estimates, one pound of wool can be spun into 20 miles of yarn.
* As wool fibers are crinkled, they trap air. The trapped air makes wool warm without being heavy. Thin wool fabrics are cool because they carry body moisture away from the body and, as the moisture evaporates, it cools the body.
* A perfectly preserved woolen sock was found buried in silt on the bank of a river in England. The sock is estimated to be 1,000 years old.
* Wool can be extended to up to 70 per cent of its natural length if it is stretched. When the tension is released, it returns to its natural length.
* Wool fiber actually has tiny pores. When it's dyed, the pores open and the dye is absorbed into it. That's why wool garments look and stay so rich in colour.
* The softest part of the fleece is the part next to the sheep. Outer edges of the fleece are used for rugs and felt.
*According to a web site, wool was the first fiber to be spun into yarn and woven.
* Seventythree per cent of the wool produced is used in apparel (clothing and accessories), 15 per cent in home furnishings, and 7 per cent in industrial felts (used for noise reduction). Wool is believed to be so strong, it's used to cover tennis balls and billiard tables and so fine, it's the choice of tailors and designers around the world.
* Low-grade wool is being developed to clean up hazardous spills. It absorbs 10-30 times its weight in oil.
