(Christmas Tree): The best way to hang Christmas tree garland is to start by attaching the top of the garland to the top of the tree with a hook or some other strong attachment. Then, wrap the garland around the tree in a spiral shape, starting at the top and working your way down. Make sure to keep the garland tight and even, so that it hangs straight and looks uniform. Once you reach the bottom, secure the garland with another hook or attachment, and then trim off any excess garland that may be hanging off the bottom of the tree.
