After living with these curtains for about a month, I decided I really am happy with them.  I purchased the white curtains for our master bedroom and am happy with how they block out sunlight but still illuminate the window with some light.  One would never know it was bright sunshine outside until you opened the curtains, but still you do know it's daylight.  I ordered another pair and after putting them up in another bedroom, fell in love with them all over.  I'm ordering my third pair today for a couple bedrooms in my house that have glass doors.  One panel for each door to replace the existing privacy curtains.
