Ah, a classic problem. It's all about the right amount of planning and patience. Start by determining the size of your tree and the number of lights needed. Next, measure out the length of the lights and trim off any excess to fit the tree. Finally, gently wrap the lights around the branches, starting from the top and working your way down. Make sure to keep the strands loose and evenly spaced for an even glow. With a bit of practice, you'll be an expert in no time!
