Interesting, Jamie, on the handbook. I have tried the inks in some pens on it and they washed ok but have not tried watercolor or fountain pens on that one as of yet. It did good with the tombows and wash though. If it proves poor on the other, I may have to revise my placement of it down one grade. Going to bring it out today and try it for a fountain pen ink sample test
thats good news for you about the Stillman & Birn. . .
Anyone ever try these Nujabi
watercolor hardbound ones?
