Ah, putting up Christmas lights is a wonderful way to add some festive cheer to your home. To start, you'll need some string lights, a ladder, and some hooks or nails to hang the lights. Make sure to choose a ladder that is tall enough to reach your roofline. Once you've set up your ladder, start at one end of your roofline and begin attaching the hooks or nails. Then, carefully wrap the string lights around the hooks or nails, making sure to keep the lights evenly spaced and aligned.
