Silk is a strong and smooth natural fiber with a characteristic, subtle sheen. It adds both strength and a beautiful drape to yarn.

When silk is blended with wool or mohair, it gives the yarn extra durability and a smoother surface. At the same time, it contributes a slight coolness that makes the material comfortable against the skin.

Silk has less elasticity than wool, but in return has a beautiful drape. It is often used in finer qualities, lace yarns or as part of blended yarns where both strength and elegance are desired in the finished knit.
