This artist from Tennessee upcycles old sweaters into hand warmers in the shape of sheep. The sweaters are cleaned, sewn, and stuffed with rice. Just microwave the little sheep for 30 seconds and it will stay warm for 30 minutes. You can tuck the sheep into your mittens or your pockets on those cold winter days. Unlike warming products in drug stores that are applied to the skin and then thrown away, you can re-heat these little sheep all winter!
