80% Superwash Merino wool, 20% nylon
From Yarn Love:
A beautiful sock / fingering weight yarn with a gloriously full body and soft hand. Enjoy the cozy, soft nature of this yarn which knits up into a cushy and comfortable sock. Due to the nylon content of the sock, you can expect the fabric to standup to lots of wear.
Note: Juliet’s yarn base underwent a small change in 2010. Yarn purchased prior to this was 435 yards per 4 oz skein, 75% superwash wool/ 25% nylon.
