I've used these for a very long time for decorating my windows. Putting lights up around the windows is a breeze! The best part is that when you want to string the lights around a corner section, you can apply them sideways to keep the light string taut and very neat. I've used them upside down, straight, sideways...you name it! The are just the right size to snap in one or both of the double wires on mini light strings. I've found them to be super secure, and I keep them up all the time, replacing the adhesive strip as needed (which isn't too often!). They also work on the window frame for hanging lighter ornaments. I also have them around the large picture in my dining room, on my walls (for making string light Christmas tree) and along the inside edge of the top of my hutch, where I have lights hanging all year.
Thank you for such an amazing product!
