Where in the middle of renovating our home and adding some major updates (hence the no trim and mismatching window treatments). This area is the hottest room in the house. It gets hit by sun at least 13 hours a day. They be ock out the light very nicely, only letting in light where the curtains open and on the ends if NOT shut or pushed up against the wall. I can't wait to see how they hold up next summer when temperatures hit  113° +. These curtains are excellent quality. They are thick and very well made. I love the feel of them. The color is the same on the other side, which I love. I've always seen it another color that looks hideous from the outside. The color I purchased is, fog grey. I find it to be true to its color.  Going to purchase more of these for sure. You will not regret this purchase!
