Thick...but surprisingly wasn't as light blocking as advertised. I've had these before in brown and were totally light blocking so I re-ordered. Color was true to picture (ivory) . I think it might be because of the color . They don't look bad but just don't get the job done. If you don't mind the light coming through its all good. I'm probably returning.  (Haven't hung them, just pulled 1 out of package to show)
