Thick and luxurious!  The “off white” is a beautiful light champagne. Looked even better after steaming creases out. Used the curtain rings recommended , but also has pocket for a rod if you choose to go that route.  Blocks out most of the sunlight when blinds closed .  Will not block out direct sunlight by themselves.  Would use with a shade or blind for best results.  Look beautiful though , if that’s biggest concern.
