diluted acrylic gesso? i picked up some regular
acrylic gesso this afternoon--what is a good dilution?
 i'm nearly out of pre-size gelatine/formalin paper
and need some alternatives fast.

thanks to everyone for the ideas.
none of my basic art supply stores carry bfk rives, is
it a specialty art store kind of thing? (i.e., out of
the league of rag shop/michael's/ac moore?)
