This is Eurydice, by SpillyJane (a pattern I’ve been holding onto from a sock club from looong ago.) The yarn is Lichen and Lace Matte Sock, in the Teal Tide colorway. I’m making these for my Aunt N. (I hope. She has size 11 feet, and I’m not positive I have enough yarn. We’ll see.)
I will say, having been working with mostly cotton yarn lately, this yarn feels so soft it’s not even funny. I do love wool.
