Is powdered pigment difficult to get into solution with the gum? I've
never tried it. I use windsor & Newton tube colors and those combine
with the gum easily and smoothly. Cheaper one's Ive tried tend to
bunch up in the solution and produce bad results. But if powdered
ones work - well w&n tube colors are expensive and savings would be
welcome.
