The Twister Tool measures 8in square and makes 15in finished pinwheels. The L'il Twister is 3.5" square and makes 6in finished pinwheels. Let's Twist by Marsha Bergren (24 pages) features a dozen patterns using both the Lil' Twister and the Twister Tools, from an apron to table runners and quilts using both sizes. The Let's Twist...One More Time! (24 pages) pattern book takes the "Twisters" up a notch with new techniques and another dozen patterns that put both twister tools together in more ways.
