The holidays are a magical time of year, and nothing sets the mood quite like Christmas lights! If you're looking for a guide on how to hang Christmas lights on your garage, you've come to the right place. Let's get started! First, take a look at your garage and decide how you want to hang the lights. Will you be stringing them along the roofline, or will you be creating a festive pattern on the side of the garage? Once you've decided on the design, measure the area you'll be covering and purchase enough lights to fill the space.
