JoAnn's has a lot of different backings to choose from. Get it when it's 50% off. If your confused, ask the women who work in there, that's what they are there for. I have used the Rain no Stain and really like that. One woman asked me to use the room darkening lining and she loves it. There is a thermal but I figured it would catch even more of my cat's fur. They even have white or ivory. I always thought they should have a dark color or dark drapes.
