Diana, what kind of gelatin, at what bloom and what percent were you using?

Of course the whole business is personal preference times the paper choice plus the sizing method, the gum brand, and your middle initial, but I don't think I've heard anyone not like gelatin, so I'm curious.

I especially wonder how you applied it... (P-F #9, page 49, has a diagram of the technique I found easiest, most trouble free and long lasting -- squeegee gently against a tilted glass after vat sizing with a drop of defoamer in the gelatin).

True, it's easier to brush size ... but that's not as profound a size, it doesn't permeate the paper the same way, AND the paper, sized on one side only, WILL curl, which is a PITA. Also IME it doesn't hold up as well through many coats & soaks. (Tho I think I said that already.)
