Create a simple coffee collar from an outgrown sweater for a one-of-a-kind gift for a friend or family member. Here's how to do it! Cut off a section of the sleeve of an old sweater roughly the size you'll need to cover a coffee mug. Sew two buttons on the sleeve in the shape of a snowman. Cut a small strip of felt and sew it on as the snowman’s scarf. Play with colors and patterns to personalize your gifts!
