and scroll down to Craft Instructors, you will learn that you can call Jan at (530) 752-3096 to inquire about instructor openings.  You might want to look at the website and see where your course might fit in.  I was told if you call and sell them on your idea for a course, it is open to instructors from outside the university community.  And I didn't see a lot of wearable art classes.  If you are looking for business, look into this venue.
