I too mix a stock pigment solution, though I hadn't thought about adjusting
color intensity by adding more gum. I guess I was worried about getting too
little pigment on the paper since I can't really see if it's too intense.

After spending several hours ripping paper, I'll try a few sheets sized both
ways and see which method works better for me before committing them all to
one method. I'll also try it with 2 coats and see how that works; my
original papers only had 1 coat. I assume you pre-shrink your papers before
brush sizing only one side?
