Formaldehyde? Do you still use the nasty stuff? What I do (after I
shrink the paper, and yes, I've had my best luck with Rives BFK) is
size it twice with laundry starch - sprayed right out of the can and
spread with a polyform brush! Its easy, its cheak, it works (My
initial instructor in alternative processes used a dilute solution of
Elmers glue!) I've tried gelatine, but why do complicated and
potentially hazardous things when there is an easier way? See what a
primative I am - I use sunlight for my "exposure unit" too!
