When I got these I was planning on putting them in the kids play room. But since my 6 yr old started back to school she wasn't wanting to go to sleep at night, so I decided to hang them in her room and try them out. The very first night she went to sleep right after going to bed. These are the best black out curtains i have ever had by far. We had some we attached to the back of her curtains but didn't help. And the best part about it is just by looking at them you would think they were regular curtains. Beautiful colors and quality material. Now need a set for my 4 yr olds room.
