I have a bow window that gets a lot of sun, too much sun.  These curtains are really good at blocking out the light.  I wanted a light color to use during the spring summer months and these fit the bill.  These are aesthetically pleasing however there are a couple of issues.  The fabric is stiff, and wrinkles are difficult to remove. Its Polyester and similar to a shower curtain in the way it feels.  These are dry clean only (not gonna happen here for 43 dollar curtains).  They are pretty, pretty at night and if you can get past the fact that the fabric leaves is stiff and shower curtain like, I would recommend.  My window is 100" approximately.  The Q&A says you need 2 panels for that length.  2 panels will leave a gap because it doesnt account for the bend of the grommet pleat, (thus my sheers).
