I'm so happy with our Silver Bahari Panels. I was cautious initially due to the cost, but ended up buying 4 panels for our wide living room window and honestly only needed 3. They are a heavy, sturdy quality. The raw silk/sheen adds a bit of chicness to it, which helps to dress up our mid-century style room. We were looking for a room darkening set of panels, which these absolutely achieve. I took this picture at the height of heat and brightness in the afternoon. Light does come through a bit, but honestly although I wouldn't say it completely blacks out the room, it absolutely darkens it significantly. I'm very happy with this purchase and plan to purchase the white for another room.
