Still life of some pretty vases against my kitchen tiles. I'm using some of the theory that I read: Hans Hofmann's "push and pull". It is essentially the simultaneous flattening and deepening of the picture plan using colour contrast, form and spatial juxtaposition. Hofmann thought that line was a weak way to show form . . . I disagree. Contour lines have in them a tactile quality: touching the subject with your eyes.
