These aren't blackout curtains.  See photo of these curtains (left) letting in sunlight, and our current curtains (right) which are actually blackout.  I ordered two curtains for our bedroom - one of them didn't even make it out of the package because there was a bright blue stain on it.  If you don't want blackout, then I think these are a really nice fabric, but if you need them to block out light then keep looking.  I'm in the latter category, so these will go back and our search continues.
