I was debating between wallpapering a wall or getting patterned curtains.  I'm pleased with the choice.  Adds interest without a long term commitment. As others have stated, not black out, but light blocking.  They are a heavier quality then expected.  I quickly steamed them and wrinkles were gone.  I did the 'toilet paper' hack, but with foam pipe insulation as grommets are wide and would show the paper rolls through. 3rd picture up shows how it makes the curtain full.  Left side has it and right side doesn't (taken in daylight, others at night).  Just cut the pipe foam the size of a toilet paper roll. My wall color is Sherwin Williams evergreen fog.  I use daylight bulbs for color reference.  Very happy with the curtains and felt the price was reasonable.
