In Mirror of the Divine by Ludwig Tuman, he writes about the difference between art and craft. They are two directions on the same spectrum. On one end is "art", equated with a greater reliance on imagination and individual judgement. On the other end is "craft", equated with a greater use of convention and a tendency to routine repetition.
As an artist as well as a teacher, I find my work wanders quite freely along this continuum. Baskets that I design for teaching in classes are certainly different from my artistic pieces, although both types require similar techniques and proficiency.
It's just nice to see this affirmation that they are so closely related, and one is not "better" or "above" the other.
