The Berry Christmas Cup Cozy is the perfect way to gift a card-with a handmade touch. Small and fast this little cozy doesn’t take much time or yarn. But it’s beauty will make a lasting impression. I love a good scrap yarn project. Crochet Pattern includes photo tutorial for this lovely textured stitch.
