It's easy to hang Christmas lights on your house! First, decide where you want the lights to go. Then, measure the length of the area you want to decorate. You can use string lights or icicle lights for the best effect. Next, use a staple gun or thumbtacks to attach the lights to the surface of your house. Make sure the lights are evenly spaced and not too tight. Finally, plug in the lights and enjoy your beautiful Christmas display!
