I've purchased a few sheets each of Fabriano Artistico, Rives BFK,  and (the
recently much discussed) Lenox100.  Of these three, I like the color and
texture of the Fabriano very much.
I'm also interested in using a pigment other than Sumi ink, which I tried in
my initial carbon prints.  I'm fortunate to have access to quite a supply of
Winsor/Newton water colors, and would like to mix a pigment color that
produces a cold black to violet black.
If anyone has suggestions for other papers to try and/or pigment
combinations,  I would be grateful.
