Like the site says, they do let some light in. It's not much but it's some that comes in. This is easy enough to fix by adding a back panel and you don't even have to sew it on, you can just get some sewing tape to tape it on and then it still removable. I love the back tabs on them they're amazing for me and what I wanted. They go perfectly with my monstera plants and that was literally the only reason I went with them ? I wanted something to match my plants. My dog seems to like trying to lay on them and rubbing against them though ? Do with that what you will. I do 100% recommend them if you like velvet!The color of these curtains is exactly as described/shown in the photo (I bought the gold ones). I loved them so much I bought a second set. They are being used in between rooms to reduce drafts (it's very open in our old house - there are no doors, just columns, between the larger rooms). The curtains are heavy enough not to blow around when the heat comes on and the rooms are noticeably warmer. I would not hesitate to buy them again.These curtains are beautiful but the shade of mauvy blushy pink is weird. When the sun is coming through them when closed, they are a horrid bright red. My daughter called the room “the vampire dungeon” because they make the room look like it’s glowing red lol! So I moved them. But unfortunately we had a brownish carpet and they take the color, making them look very brown and not pink at all. ?. I kept them and tried them in our bedroom- cream and blush rugs and no direct sunlight through the window and they look great! Good length, not very thick or heavy, very soft. I still like them. I ordered 2 sets for a total of 4 panels to make the look more substantial. They are not very wide.GREAT quality! I was super nervous of what they’d feel/look like in person and I couldn’t be happier. Definitely worth the money! Super thick and block out the sun and the most buttery velvet material. 100% recommend!The quality of these curtains is outstanding! I was looking to shake things up for a warmer-fall vibe and these executed just that. They are super soft and look fantastic. The only downside is they do let some sunlight through but I don’t mind that at all. I will be buying more!Great quality and effective and blocked sunlight. These look and feel more high-end than the budget friendly price tag. I purchased them in black and the color is rich and consistent throughout the panels.These gave our music room elegance and warmth. The fabric is very nice. While they are not lined or weighted, they hang very straight. The tab tops are great.Make sure you steam them. Look so beautiful!Buen material
