We bought the turquoise panels and I purchased two sets of 2 panels as the stated width was going to fall a bit short if I only purchased one pair to cover our slider.  They are a great weight and offer plenty of coverage without being "black-out" curtains.  Enough light filters through to know when morning has come!  The velvety material is luxurious feeling but still manages to look casual chic and not pretentious.  Perfect complement to the modest updates we made to my daughters small bedroom.
