Improv art is a form of art invented by A. Otterness in late 2004. Improv-art is usually used with the medium ink and
metal brush on thick watercolor paper. You
dip your
metal brush into your ink and you make up your painting as you go. You have no rough draft, no pre-drawing, no tracing; just let your immagination flow through your metal brush, and into the ink that stains the paper.
