kevin, try Masa paper it's perfect for all iron / iron-silver processes and it's cheap too. (Something like USD 1.2 - 1.3 per 21x31" sheet... I remember the times when it was only USD 0.7/sheet.)
Loris, am I miss reading what you say here, as with Cyanotype you don't need an emulsion (by that I mean gelatin).
