Did you know?
Wool is elastic. The crimp along the length of the wool fiber allows it to be stretched up to 50% of its length without breaking or to be crushed and resume its original shape. When released it "remembers" its original length and returns to it. That's why wool carpets remain springy, and wool clothing is resistant to creasing and recovers from wrinkling after hanging. This elasticity is also why 150 yards of wool yarn are used in an official baseball, and why wool felt covers piano hammers. Wool's elasticity also allows it to be bent 20,000 times without breaking (compared to 1,800 for silk or 70 for rayon), making wool garments very durable.
Thank you for the wool facts! I love wool... it's good to visit your blog again.
