These curtains are absolutely beautiful and they genuinely do a great job darkening the room. I have orange blackout curtains hanging in my living room and I added these to the window (while my old curtains were on the rod beside them) for a comparison, and even though these are lighter, they did a much better job of blocking out the sun and bright headlights from the store across the street at night. 

They are thick but not heavy and do not weigh down my curtain rod and the large grommets make them easy to slide on a curtain rod and install in just a few minutes. I really like the print and I would definitely purchase more curtains from this company for the other rooms in my house.  Most sun-blocking curtains are usually solid prints and it can be hard to find stylish ones, so these are great.
