That's a great question, and it can be tricky! First, you'll need to choose the right type of light for your house. Outdoor lights are typically more durable and weather-resistant, while indoor lights may be easier to hang and remove. Once you've selected the right lights, it's important to plan out your design and consider the location of any trees or bushes that may block your view. Once you've planned out your design, it's time to start hanging the lights. You can use a ladder or a step stool to reach higher areas, or you can use an extension pole to reach the roofline.
