All my socks are black, so I'm not too bothered if I make a pair out of a newer still very black sock and a faded one. Husband is evangelical about socks matching, and he will buy the ones that have a different colour on the toe bit so no chance of matching those up, also has beige ones for summer, but again all different so can't be matched. As a consequence he has a drawer full of odd socks, alas no partners. I do believe there must be a land somewhere out there that is inhabited by lonely single socks, it's one of life's great imponderables where do socks go once they go in a washing machine in twos but come out as singles
