"Hanging Christmas lights can be a bit tricky, but here's a step-by-step guide to help you get the job done efficiently and safely. First, gather all your lights and determine how many you'll need to cover your home's exterior. Next, plan out your design and measure the length of your home's roofline and eaves. Then, using a ladder or a stable platform, start by attaching the lights at the highest point of your roofline and work your way down. Use a staple gun to secure the lights to your home's exterior and test the connection to make sure they're secure."
