These blackout curtains are absolutely amazing! They are inexpensive but very well made, and the fabric successfully blocks out 100% of the light (though a small amount "seeps in" around the edges). They The only [slight] complaint I have is the fabric is shinier than I expected. If I had seen the curtains in the store, I might not have chosen them for that reason--which would have been a shame because the shine doesn't show at all once the curtains are hung. I highly recommend these curtains--for shift workers or anyone who may benefit from a very dark, quiet room.
