It's easy! First, make sure your tree is properly assembled and standing upright. Then, take your strand of lights and begin wrapping them around the tree, starting at the top and working your way down. Make sure to evenly distribute the lights so that all sides of the tree are equally illuminated. If you have any extension cords or wires, make sure they're hidden and secured so they don't cause a trip hazard or interfere with the beauty of the tree. With a bit of patience and care, you'll have a stunningly decorated Christmas tree in no time!
