I just spent a week in Arizona working with Katherine Chang Liu, an internationally recognized artist and teacher. Katherine calls what she does mentoring, not a workshop, partly because she does not demonstrate techniques.
Katherine does not dwell on an artist’s deficiencies, instead she identifies each individual’s strengths and guides them by building upon these strengths to form their personal visual language. Her ability to discover the essence of each artist’s work was amazing. At least in my own personal case, it was positive reinforcement.
Although my work space was totally mine to organize and set up, I was fortunate enough to be near two incredible abstract artists, Nancy Dini, and Jackie Roliardi. Nancy was working with texture and Jackie with shapes. Observing the various artists and how they worked was an added benefit of the week.
