David,

At the carnegie Museum we recently tested some cotton that was yellowing.
It tested as being very acidic. Other samples of cotton were more neutral.
If you use cotton, buy a good grade and get a pH Testing pen to see if the
cotton is acidic. These pens are most readily obtained from companies such
as Light Impressions (where I bought mine), University Products, and
Gaylord.

Regards,
Charlie
