This is 100% BFL - Blue-Faced Leicester. It’s like knitting with kevlar. Ok, that’s a giant exaggeration; it will not stop a bullet. But this stuff is tough thanks to 8-plies of 100% BFL superwash wound round and round. Fantastic for shawls, especially lace work thats lends itself to the strength of this yarn.

Also sold in 100 grain. skeins.
