..as I posted before I also had problems with VDB: yellowing and
"bleeding" in the fix. bath. This was with Fabriano Artistico (which gave
beautiful Cyanotypes btw, as you also found). My problems with VDB were
solved by changing paper, in my case Canson Fontenay
(sp?).., gave also nice Cyanotypes, but not as rich/dark blue as on
Fabriano though..
