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.

With the thermal insulation, we can really tell the difference in our kitchen, from closed to open, really keeps the heat out, and we live in south Texas. Impressed for sure, thanx.

I bought this curtain to cover a sliding glass door to keep it cooler in my bedroom. It works great! It keeps my room nice and cool and super dark at night! Well made. Good and thick!
