The fabric of these curtains is thick and velvety, similar to flannel, and they are the ideal color for our guest bedroom. My brown 84-inch L. Very much what we were going for, a cabin atmosphere. They appear to be effective at blocking out large windows as well. Pictures show both with and without the room lights on, and they perform better than expected at blocking plenty. Most of the time, the wrinkles smooth themselves out over time. Without a doubt, I would buy these again.
