Bought these for our bedroom. They do not block out all light, although they are pretty thick. Layered them with sheers for privacy. Love the way they look. Seems like in the description they were said to have vertial ruffles, so something like that. Not sure what that means, they are just normal curtains that gather when pushed together. I would think you could use these in just about any room.
I had been eyeing these for a while and when they dipped below ***, I ordered four pair. I was very disappointed. the picture makes them look very stylish, but these curtains just look like bedsheets hung from a rod. I will be returning them.
