These curtains are great! They are pure white, super thick and definitely black out curtains. They also seem to be helping with keeping a large room with lots of windows warmer at night. I hung these on a double rod and put them at the back with sheer panels on the front. They were a pretty good price because it seems you really get what you pay for when it comes to curtains. I would definitely recommend these, and love that they came as a two pack instead of single panels. Great buy!!
