I was expecting more of a heavy cotton or polyester fabric type window panel. The type that's pretty standard no matter where you buy. I was surprised to see how shiny or slick or how much of a sheen these had. It's a little difficult to explain, but it's almost something you'd expect to see on a shower curtain rather than a window panel. They're heavy panels and seem to be good quality, but I haven't yet hung them because I'm not sure I'm sold on the fabric.
