A while back I bought a couple balls of yarn for myself while buying birthday yarn for my sweet mother. Isn't this lovely?
It's been lying around teasing me, but now I found this wonderful pattern on Ravelry's pattern database called Kalajoki. It's named after a river in Finland and it looks like a river flowing down the sock.
I was a little worried that the different colors would break up the pattern, but I think it will work.
