Here is the pattern that was designed to be used as part of the Advent sockathon make-along. If you'd like to join this year's knit along, the information is on the Germander Cottage Crafts Blog. I also have a Ravelry group!
This mini sock is knit from the cuff down in DK yarn and promise a quick project. The gusset heel is worked without the need to pick up stitches, and the sock is finished by grafting the toe stitches together using the kitchener method.
