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.
