I have these curtains in a couple rooms and just bought for our living room french doors as "summer" curtains to hopefully block out some of the sun/heat.  In our bedroom, we have the ivory, they do a great job of blocking out the light at night and layer nicely with the Serendipity curtains.  They are a very sturdy material but do not look too heavy on the window - somewhat sheer but you cannot really see through them.  I have had for almost 2 years and they still look great.  

Pros: block out the light, good quality, classic look
