Ok, well you can't see the finished sock - it is drying. But here is all that remains of the hank of yarn.
Sure makes me nervous. What you see is some of the yarn split, and 109cm (43") from the cast off edge. I can see the beauty in doing toe up socks. I was antsy to block so I haven't weaved in the other end, but it isn't long either. I'm off to start the second sock.
