I LOVE these drapes !!!!! They are so easy to maintain, just follow the directions in the package when you get them. Throw in dryer on LOW with a damp hand towel and hang.  I was so impressed with them that I used them for every room in my new house, different colors and style for the living room. I suggest sticking with no less then the middle stage, the " Thermaweave " . I have seen a difference in our electric bill. We even did our patio sliding glass door, it can get very expensive so watch for sales between Wayfair, Kohls and even Walmart.
Wayfair was very accomodating and helpful, which has encouraged me to do more business with them. This says a lot because I am not one for shopping online. I hope this has been helpful and sorry that it was so long.
HAPPY SHOPPING!!!
