Nice looking blackout curtains, even indoors

The blackout of these curtains is true. I'm using them indoors and they're serving their purpose so far very well. They slide easily on their sturdy grommets and look nice.

Perfect for FL Room

Perfect bright white curtains for my huge FL room windows. They have the appearance of cotton, which I like, so they don’t look like cheap polyester curtains. They certainly cut down the glare in the room and make it easier to watch TV but they aren’t completely black-out curtains. The wand makes it so much easier to open and close without having my kids touch the white curtains

Beautiful and efficient heat blocker

Lovely curtains that exceeded my expectations. They serve as an efficient blocker of the sun's heat from my patio door and prevent the inside temperature from being affected. I highly recommend them.
