I love these curtains. They are very well made. They look amazing and are great at blocking out the sun. On some of the windy nights we've had lately They were also great at blocking the air from blowing through our old window frames. I work 3rd shift so I'm usually trying to rest during the day and having the light blocking curtains are a huge help. They seem like they will also be useful in the colder months to help block out some of the colder air and help keep heating costs down.
