Let me tell you all about the art of putting Christmas lights away. First, take down the strings of lights from the trees and other places they were hung up. Then, untangle the lights and wrap them up carefully, making sure to avoid any kinks or tangles that could damage them. Next, store them in a cool, dry place away from any direct sunlight or heat. Finally, label them with the year and where they were used, so you know exactly where to find them when it's time to put them back up again.
