Very pleased with these blackout drapes! They get the job done. I previously had wood blinds with gorgeous crushed taffeta drapes that matched my bedding perfectly. Unfortunately I suffer from migraines and if I sleep in on the weekend, the room can get bright, and this makes me feel pretty bad sleeping in a room with sunlight. This brought me to search for blackout drapes. I was having a tough time finding gray ones. I finally found these and after reading all the good reviews, decided to give them a try. The gray isn't exactly the gray I needed, but that's my own fault, and it still looks good enough! I was actually able to layer these behind my other drapes and they sit together very nicely! I use a curtain rod with rings with clips, and the clips hold both sets of drapes. Putting them directly on the rod would have worked well too, but the rings allow them to open and close very easily. Overall, it's an attractive look having the two drapes layered together, and it adds much darkness to my bedroom. They do block out almost 100% of the light, but remember that unless you have it perfectly flat and sealed over a window, light WILL come in around the edges, but this is true for any drape. I just do the best I can with it, and it works very well. I'm very glad I gave these a try! I would recommend them to anyone needing darkening drapes. They are good-looking drapes and there are so many colors. Give them a try!
