Now that the holiday is over, what's the best way to store an artificial Christmas tree? Many people like the convenience of an artificial Christmas tree, but storing it can be a pain because it takes up so much space. Here's an idea: Buy two 8-in.-diameter concrete form tubes, wrap each layer of the tree in twine and shove half of the tree layers down each tube. Mark the layer numbers on each tube and slide the tubes up in your garage rafters for a perfect storage solution! Need more more storage space for your tree and other Christmas decorations?
