I already have a set of these curtains in my guest bedroom, and everyone who ends up staying over always asks where I got them because they love how well they work. when you close the blinds it can be the middle of the day and it will feel like the end, it's nice and dark and really helps when you need to get some rest at all times. I also love them because I can keep them shut and save so much energy cooling down the house, it does a fantastic job blocking all the heat. Must have item for anyone, they really work!
