Hello there! When it comes to hanging outdoor Christmas lights on your house, there are a few things to consider. First, make sure you have the proper equipment, such as a ladder, a strong hammer, and nails. You may also want to use outdoor-friendly lights that are designed to withstand the elements. Next, map out your plan, and start by hanging lights around the roofline and over the front door. Then, add lights around windows and trees, and finish by outlining the roofline with lights. Don't forget to use a sturdy extension cord and a surge protector!
