Have some old keys in your junk drawer? Did you know you can use them to help the homeless? The Giving Keys, a nonprofit based in Los Angeles, works with homeless people and trains them to make jewelry out of old keys. The keys are upcycled into rings, pendants, bracelets and more. The workers earn an income, and it helps them get off the streets and back on their feet. To learn how to donate your keys, or to shop the collection, visit thegivingkeys.com.
