Putting Christmas tree lights on is an essential part of the decorating process! To start, take the lights and gently wrap them around the base of the tree. Then, slowly work your way up, making sure to space the lights evenly around the tree. Once the lights are in place, turn them on to make sure they are working properly. If any bulbs are out, replace them before continuing. Once you're finished, stand back and admire the beautiful light display!
