I usually mix 4 tsp solution for a certain number of prints, or 8 tsp for a
certain number of prints. That means, gum/pigment/dichromate. I always mix
a little extra because there's nothing more frustrating than running out of
the mix in the middle of a large print. So usually, 2-3 11x17's will be 4
tsp, and 6-8 I mix up 8 tsp. Sometimes with the 6-8 number I'm scraping the
bottom of the cup pretty drastically :)

I actually have this system pretty simplified--I use the same old teaspoon
measure, and know that 2 squirts of my dichromate eyedropper is a quarter
tsp. And, all my pigments are premixed in gum.

I'm so excited; this weekend I'm holing up and gum printing with 8 new
prints! Anything to get my mind off the fact that I came home tonight and
the construction crew that is re-siding my house just replaced the front
door and there's NO door knob and NO lock. And it's the weekend. Hmmm.
