I got the Blakesly Printed Ikat Blackout Panel last week and hung it up in my office to reduce glare from the sun. It works very well! I don't see any light come through the panel at all. It is a very pretty design as well which you don't have many options of when looking for blackout curtains. I will have to get another one to match as this pack only came with one panel. I highly recommend this brand!
