This is the “Try This” Pattern at the end of Chapter 2 on pages 33-34.

Pattern Description from Zen and the Art of Knitting: “Make a scarf for yourself or someone you love…The scarf will curl in towards itself in a cozy way. For a variation, change yarn colors as you go (orange and lime, or whatever color combination gets you going - you can even use up your leftover wool, changing colors whenever the skeins ends). This prismatic scarf will add brightness to the dreariest day and remind loved ones of the colors they add to your life.”
