They are pretty curtains.  They hang beautifully and have a very elegant appearance. They are certainty worth the money.  I can't say they are blackout curtains. I have one panel of these curtains hanging next to a true blackout panel and there is a significant difference. They do block some light but if a true black out is your goal, this is not for you. Granted, I purchased a light color which is not the best option for blocking out all light.
