Fleece Your Feet is a fun sock pattern that calls for holding two fingering weight yarns together to get a DK-weight yarn — however, a single DK strand works just fine as well. As written, the pattern combines the warmth and softness of alpaca with the structure and stitch memory provided by a Merino/nylon blend. Use two skeins of the same colorway for a harmonious blend, or two contrasting colors for fun visual interest.
