Wrapping-paper, paper-towel, and mailing tubes have never looked so fine. To upcycle yours into something front-door-worthy, use an X-Acto knife to cut each tube into two-inch slices. Then, lay a bowl (ours measured six inches across) rim down on a flat surface and arrange the cardboard slices around the bowl, using this photo as a guide. Hot-glue the slices where their sides meet. If you like, perch jingle bells inside.
