Keep your mug toasty warm this winter with a sweet knitted mug cozy. Liana Allday shows you how to knit this tri-colored cozy in linen stitch. Along the way, you'll learn how to keep track of right and wrong sides and which color you're using, and how to create a button loop by chaining with a crochet hook. The resulting cozy makes for a great holiday gift, especially when paired with a special mug.
