how to attach christmas lights to windows

Well, if you're not too good with electricity, I'd recommend using command hooks and LED fairy lights. You can get command hooks in different sizes and shapes, so you can attach them to the window frame or even the wall around the window. Then, you can hang the fairy lights on the hooks. Make sure to use enough hooks to support the weight of the lights, and make sure they're securely attached to the frame or wall. And of course, always remember to be safe and follow all electrical safety guidelines!
