Throughout the years I’ve gone through different sets of curtains. These are by far the best ones ever. When you think of room darkening you expect it to be just that right? I’ve been let down many times from different ones. Till now when I’ve found the perfect curtains for us. My boyfriend works nights so he sleeps during the day. We get hit with tons of light and heat. You can literally feel the heat as you stand by the windows. So I put them up when the window has the most direct sunlight and I was thoroughly impressed. It was like night and day! Not only do they block out light remarkably but they also block the heat. It has made our top floor apt so much cooler which I’m sure we’ll notice a difference in our bill that’s how well they work. Definitely will be getting more to cover the rest. You won’t regret these they truly are awesome they’re thick stitched really well. Pictures attached are minutes apart.
