Don't know what to do with old gift bags and boxes? Simply save them again for later use, such as bringing snacks to a party, or reuse them as a gift box. For example, if you had a box filled with cookies for your birthday, you could use the cookie box to regift someone with cookies of your own! This easy and convenient process limits wasteful paper production, and you'll be glad to know you're helping to make an important step in saving the Earth.
