Many students who used the Elementary workbooks and completed the Zennergy Intermediate and Advanced course levels went on to become Certified Zentangle Teachers (CZTs). The Intermediate and Advanced Workbook is for art students who have completed elementary training and wish to take their capabilities to new heights.

These books are created using the finest paper, handcrafted from waste cotton by “tribal women” of Gujarat, India. A portion of the proceeds of the books goes to them.
