Beautiful medium weight fabric with a silk look and feel without the shine. The panels are definitely "room darkening" not blackout curtains. I just added a couple of sheer panels to get a little more light filtering. Four panels were used to achieve fullness with the rod extended out ten inches to maximize window and the rod was mounted all the way to to ceiling giving a kissed length, but these could easily be beautifully puddled in a low traffic area. Will definitely look to these again in the future.
