Why We Love Wool
Wool has been a trusted fiber since ancient times and it resists dirt and is easy to clean.
100% Tencel yarn is great for weaving and can be used for warp or weft. Tencel is made from cellulose fiber from trees. It is shiny and very strong.
The yarn is put up in 8 oz tubes and weight is 8/2 with approximately 1680 yards per tube. Sett = 15-24 epi.
