It's the Waving Lace sock from Favorite Socks. I'm knitting them in Socks That Rock Blue Moonstone. I love this yarn.
Did you notice that there's only one ball of yarn, but two socks attached? Isn't that neat? One sock on each end. I'm just making sure to keep the one I'm not working on in my knitting bag so there's no tangling. So far so good.
I'll be finished the legs of the socks tonight.
