Curtains are fine, simple and elegant. They do block the cold coming off the window. Followed the directions to unwrinkle them, worked fine. 
Very unhappy with the Fed Ex driver who threw the package from his truck onto my neighbours porch and drove away (witnessed). Luckily it wasn't anything breakable because the box was smashed in on one side and also that my  neighbour was home and is our friend since it was delivered to the wrong address!
