Don't worry, I can help you with that! The first step is to get a string of lights that are suitable for a real tree. Then, start by threading the lights around the trunk of the tree and up the branches. Be careful not to twist the lights too tightly, or they may break. Once you've covered the trunk, move on to the branches, making sure to spread the lights out evenly. Then, plug them in and enjoy your beautifully lit tree!
