Oh, I'm so glad you asked! Christmas lights can be a tricky thing to put on a tree, especially if you've never done it before. But don't worry, I'm here to help! First, make sure you have enough lights for your tree. You'll need to measure the width and height of your tree, then add those numbers together to figure out the total length of the lights you'll need. Once you have your lights, start by plugging them into the outlet, then begin wrapping them around the tree from the top down.
