This fiber comes from the United States.
The old Teeswater sheep of the eighteenth century was the largest and oldest of the longwool breeds. It evolved near the River Tees in the northern Pennines. The Teeswater breed declined in the 19th Century, but was revived in the 20th by the formation of a breed society in 1949. It declined again thereafter, but is still a popular breed due to its long, lustrous wool and heavy carcass.
Teeswater fiber is long, lustrous, white and kemp-free.
