A Primer of Organic Form – “Organic form is an oxymoron — form implies a repeatable technique, and organic suggests shape devised for a specific instance. This brief booklet is a primer of how to marry the two together: how to use pace to control a verbal experience to achieve a desired result. Organic shape is the last (largely) unexplored means of presenting haiku, and a challenge to the poet as viewer as well as writer.”
