Oh, you're in luck! I've got the perfect tip for hanging Christmas tree lights. First, make sure to start from the top of the tree and work your way down. This will ensure that the lights are evenly distributed and look nice. Then, try to wrap the lights around the branches as you go, rather than just hanging them from the tips. This will give the tree a fuller, more festive look. Finally, use multiple sets of lights if you have a big tree, so you can make sure that every branch is covered.
