We have a game room in my house and my sister is always annoyed that sunlight is always coming through the blinds. I was very excited to try these blackout curtains out to see if it fixed the issue. Let me tell you, these curtains exceeded our expectations! When you close them you can’t see any light at all and completely blacks out the room. It also helps keep the room cooler which is a huge plus! Overall these curtains are amazing and I highly recommend them to anyone trying to keep the light out!
