I love to decorate for all the seasons. I even hang pink lights up in spring inside around my windows. Since the command photos showed hangers on lights outside of windows it has to work on inside of windows. Right? No they don't. Followed the instructions for placing the hangers. My husband and I put the lights up together a round my big front window inside. I was so happy it looked great UNTIL... I heard a pop and all the lights fell off on the floor. The lights were very small LED lights that that had no weight at all. It looked so nice and organized after we first put them up. I traded my ugly thumb tacks for the command hooks. I just wish they worked. How disappointing. I had so many great idea and uses for the command products I had in mind. I am very sad. I love to organize its a pass time yo could say. So that really adds to my sorrow all the great ideas that I will never get to try.
