The white is really a white !  Matches my white cotton bedspread perfectly.  I will put over my cotton white honeycomb shades very soon.  The fabric is medium; not a gauze yet you can see right through the material when you hold it in the sun.  They are wrinkled from packaging and they say no iron and dry clean only.  This perplexes me, as I have linen sheets and throw them right into the washer / dryer and they are beautiful (wrinkles, yes but that is non formal linen).  Can't wait to install these. Feel decently made.

Pros: Right Color (white is not off white).  Right texture not too sheer (gauze) not too thick
Cons: Not sure yet
