I was so surprised with these Grommet panels.  There is a backing to keep the sun out.  I placed them in my loft near the computer.  When the sun comes around to the window, all I have to do, is pull them closed.
Nice pattern--works great with my chair.  The pattern is a soft swirl and kind of matches the swirls in the easy chair.  It is really PERFECT.  So happy I purchased these.

Pros: Hangs well--Grommets make these panels look---rich
