I’m using these curtains in my classroom and I’m very happy that they keep out the light that I can still show a video as it keeps the room dark enough. They make the room feel more homey with the design. I have 5 very large windows in my classroom that are on the south side, so it gets warm in my room. I’m hoping these curtains will keep my room cooler. I had a flaw in the material of one curtain and Wayfair quickly replaced it with no hassles! Thank you Wayfair!
