It is so hard to choose curtains online without feeling them and seeing the color in person. I took a chance on these as the price was amazing and am SO GLAD that I did. These are super heavy, well constructed and the grommets are beautiful. They block most of not all light. I got the grayish white color and it is a beautiful very light grey. They also help keep my great room warmer. The ambient temperature in the room has been 3 degrees higher at night with just the addition of these over the sliding door. Well worth the price and will be ordering more for other windows around my house!
