Ryuji,
I've sized many a 16x20 sheet of paper with this dilution and it works just
fine with Knox. I even tried the 3 ml and it worked fine, too, but prefer
the 6ml to 1000. But I am not gonna say that 6ml/1000 is gospel, just in
practice it works perfectly for me with just the normal food grade gelatin.
It'd be interesting to test it at the opposite extreme (lots more) and see
what effect it has.
