I find this interesting Judy. I have never diluted my gum with water -
though I often use more sensitizer than gum/pigment. But your comments
are useful as I have had problems with too thick a coat causing flaking -
with your favourite paper - Bockingford (which I have decided to stop
using forever - :-) ) I will have to give this a go. Sorry for missing it
earlier, but what kind of ratio of water to the gum/pigment are we
talking about here?
