Our neighbors installed exposed string lighting all along the perimeter of their fence. We have two small windows above our bed and even with Levelor blinds, the bright light was seeping in and keeping me awake. I chose these to go right over our current blinds as an extra layer to darken our room. They do the job nicely, look lovely with our curtains on the big window and I love they just roll up during the daytime hours. My husband had no problems installing them and I’m very happy with my purchase. Thanks, Wayfair!
