THESE CURTAINS ARE AWESOME!   They are 100% blackout.   I washed them right out of the bag to soften them up and smooth out the folding lines.  They washed and tried perfectly.  I bought enough to use for all my windows in my Family Room.   I have an older house with the original 1950's windows, so the big picture window is not really energy efficient.  These curtains keep the heat out in the summer, and the warmth in during the winter.   
I highly recommend.  A nice off white/lt beige color.
