Alpaca have been prized for their fiber since Pre-Incan times due to the properties and quality of their wool (hair). Alpaca is Softest, warmest fiber in the world! Alpaca is three times warmer than wool because of it's hollow fiber, yet super soft and not in the least bit scratchy. Baby alpaca yarn does NOT come from baby alpacas. Alpaca fiber is classified not by age of the animal, but by the diameter of the hair. Baby alpaca is the finest, softest fiber, and it is highly prized for rugs ,knitting and other crafts.
