Putting lights on a real Christmas tree can be a bit tricky, but it's also an essential part of decorating the tree. Start by deciding where you want the lights to go. If you're going for the classic look, you'll want to wrap the lights around the tree from top to bottom, making sure to evenly space them out so the tree is fully lit. You can also get creative and try different styles, such as draping the lights over the branches or wrapping them around the trunk. Just remember to be careful and not overload the tree with too many lights!
