When I cut off the end of a green cabbage to make a salad, I noticed the intricate, floral-like design of the piece of cabbage. I set it aside to try it as a stamp with Green Gold acrylic paint over an intuitive watercolour on paper. Here is the stamp and a few imprints as an example, not yet meant to be a completed painting.

Cabbage Stamp and imprint in acrylic over watercolour.
Love it. Healthy art.
What other vegetables do you think would make good stamps, Judith? Perhaps the end of a stalk of celery?
