The good news is that these curtains are just about what the description offers. They are petroleum-based fabric that serves its darkening and insulating purposes well and even looks good enough. But they certainly offer no glamour or upgrading. In fact, one of their virtues is that they seem to recede into the background of the room. If I remember to pull them, the following morning the room is less chilly than if I do not. I like that. I will say that if I wanted badly enough to keep things warm or dark, I would buy two sets and have them hang more loosely. As it is, I am covering 86 inches of window with 84 inches of curtain and getting an acceptable minimum of return. Two other notes. The grommets are good and large making it easy to open or close the curtains with little effort. And, the olive color I ordered was much as shown and is not garish or cheap looking. I'm satisfied all 'round with this purchase including the rapid shipping and condition of the curtains on receipt.
