I have many of these and love them.  They are a bit expensive but I am glad I got them.  They really make my bedroom feel calm and peaceful when paired with my decorative curtains.  I wish they were sold in a pair though because then the seam for the double layer could be on opposite sides, as it is I have one seam in the middle of my window on the right panel and just a nice fold on the left panel in the middle of the window.  The white is true white without any purple or blue tones.
