I use a .13 Rotring rapidograph in my daily comic strip diary but I draw my comics with a #2 series 795 Loew-Cornell round watercolor brush and Dr. Martin’s tech black ink on 4-ply Strathmore bristol board. I use a Namiki Falcon SF fountain pen that I’ve sort of filed down a little when I’m drawing in my regular sketchbook. Has anyone else noticed that the paper in those Moleskine journals is actually printed with yellow ink?
P.S. I’d add Hokusai to the list.
