Give bits of ribbon left over from gift wrapping a new life as merry tree ornaments. The ribbons' colors and patterns don't need to match exactly, since their simple shape will tie the look together. Begin by knotting scraps into basic bows around a few inches of floral wire. Next, twist the wire to secure the bows to tree branches, indoors or out. To remove the ornaments, untwist the wire, and store flat between layers of tissue paper.
