Well, my little elf, let's start with the basics. First, you'll need a tree. A real one is best, but if you don't have room for that, an artificial tree will do. Next, you'll need some lights. There are many different kinds, but I recommend using LED lights because they are energy-efficient and last longer. Make sure you get enough lights to cover your entire tree. Once you have your tree and lights, it's time to start decorating.
