That's easy! First, you need to find a good quality piece of wood. You want it to be sturdy, but also easy to work with. Once you've found your wood, you'll want to cut it into a triangle shape. This will be the base of your tree. Next, you'll need to drill a hole in the top of the tree for the lightbulb. Then, you can add decorations like garland and ornaments. Finally, you'll want to secure it in place so it doesn't fall over. That's it!
