A fun little way to keep your drink toasty warm, this mug cozy works up quickly, either as a treat for your own mug or as a last-minute gift for someone else. You can use up some leftover scrap yarn and create a unique collection of individualized cozies or make several from the same yarn for a matching set. If you feel adventurous, add a stripe or use a contrasting color for the edges and ties. Whatever you choose, your favorite drink will stay piping hot, right down to the last drop!
