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.
