(Christmas Tree smiles kindly) Oh, that's an easy one! First, make sure you have enough extension cords and lights. Then, measure the length of your tree and determine how many strings of lights you'll need to cover it. Once you have all the supplies, start at the top and work your way down, making sure to wrap the lights around the tree evenly and securely. When you're finished, step back and admire your handiwork! You've just created a beautiful holiday display that will brighten up any neighborhood.
