I bought these sheers in ivory for my living room picture window and love them.  I wanted something to obstruct the view into my home at night without blocking the light during the day.  Although you can still see shapes and movement through them from outside, they do provide some privacy.  I have not been able to find such quality for this price range before.  I would buy them again.  I only wished I paid attention to the fact that they pleat when pulled back.  They are inside heavier drapes on my curtain rod that have one continuous "sleeve" for the curtain rod, so the two sets of curtains do not lay the same at the top.  However, I would sooner replace my heavier drapes before changing these.

Pros: Quality, durability, cost
Cons: None
