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.

update to these

If you have the old vertical blinds on your sliding door. Time to get this curtain. The visual appeal. The ease of opening and closing. I should of switched years ago. I installed on a 1" rod and it looks great. Well made, it blocks the heat and the light that pours in from the deck. Just a great product. Do yourself a favor and get rid of those 1980 blinds that never close right. That usually has a couple blinds that are twisted the wrong way and make that annoying sound Everytime the wind blows.

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
