Lovely Flocculation and Granulation

I save scraps of paper from my finished paintings to test how pigment mixtures will flow wet-in-wet. I save my samples as a reference for future paintings. These are just a bit larger than a deck of cards so that I can shuffle through them (I have over 100 samples at this point). One of my sons gave me a plastic storage tomato a several Christmases ago which I trace around to make the circles.
