Thanks Joan for your kind critique. Although I belong to the
(American) National Society Of Painters In Casein & Acrylics, Inc., I
mostly paint with acrylics. I do this because many years ago, I
developed a allergic reaction to oils and their solvents. It is my
understanding that casein paints are derived from a milk protein. Hope
that helps. Good luck with your attempt at the direct-massing
technique.
