8" double sided adjustable round chart (aka volvelle). Turn the dial and discover cognitive solutions to 16 different kinds of worry complete with a Hebraic Proverb for each. . Graphic designer and volvelle historian Jessica Helfand says, “Erik Johnson’s Positive Turn wheels reveal the degree to which paper tools retain an almost uncanny authority over problem solving. With wheels offering solutions to everything from personal regret to marital discord, this series of contemporary volvelles will be appreciated by therapists and ephemera collectors alike.” (Jessica Helfand, author of Reinventing the Wheel, Winterhouse Press, 2005).
