I was determined to finish these by Boxing Day. They were a joy to knit even though when I saw the yarn for the first time, I have to admit, I hated it.
I would never have chosen it myself, but it was part of a yarn of the month club I was in at the time.
It's called Night Mail by The Yarn Yarn, base yarn is clan. The pattern is Grumperina's Jaywalker which is a free download on Ravelry and extremely well written.
