My most basic criteria:

Will it survive washing that is done with moderate care?

Is it about the same weight as most of the other fabrics in the top or back? I have sort of a bias against mixing weights such as heavy denim with gauze - the reason being that I don't think they will wear out at approximately the same time.

Can I clearly read newsprint between the threads?

There is a difference between "thin" fabric such as a high quality batiste that is used in christening gowns and "thin" fabric such as bandage gauze.
