Maria Canals Barrera: Hi, everybody, I'm Maria Canals Barrera from "Wizards of Waverly Place." And my green tip of the day, which I love to do with my kids, is to save beautiful boxes. So many gifts we get ... gorgeous boxes — perfumes, and jewelry, and I always have a problem just chucking it, because they're so beautiful. So we like to put our hair barrettes in them, we like to put our bobby pins in them, we put our soaps in them, cotton balls — they're decorative and beautiful. So why throw it away?
