I'm away from home at the moment - in Coventry for a conference - so I brought some knitting to keep me company on the train, and in the hotel. I just had a toe to kitchener to finish the pair currently on the needles. There was almost nothing left over, just a few centimetres of yarn.
As usual, I striped the socks using 2 yarns - although the effect is quite subtle because of the colours I chose. You can see the difference in the cuffs.
