It's actually quite simple. All you need is a few strands of lights, some branches, and a little bit of creativity. Start by placing the branches in a circular pattern around a central pole. Then, wrap the lights around the branches, starting from the bottom and working your way up. Make sure to tuck in the excess wire so that it's hidden. Once you've finished wrapping the lights, you can add decorations like ornaments, garlands, and a star on top. Voila! You've got yourself a festive and cheerful Christmas tree made of lights.
