I'm making progress on the second Up-Down Entrelac sock (from Sock Knitting Master Class). I decided that there's no reason for socks this wild to match so I'm choosing the colors randomly for the mate. Still, there's a lot of similarity between the two.
For this sock, I'm making a point of starting each new color in a different place so that all of the yarn ends aren't woven in the same area.
I really am having fun with these socks!
