The always awesome and incredibly clever Karen Bertelsen from The Art of Doing Stuff came up with one of the best alternative Christmas tree ideas I've seen in a long time: a space-saving, wall-mounted twig tree! Want to make one yourself? Here's what you'll need!
Find as many near-straight sticks as you can get your hands on. Also grab some "removeable poster tabs / tape tabs"; 3M makes these. After that all you need are your decorations and Karen's fantastic (and humorous) tutorial! Happy twig-tree making!
