For many years I worked as an Artist in schools with Creative Partnerships and now sometimesI run workshops for the RWA Drawing School in Bristol. The most recent was Making a Sketchbook. Last year I ran Drawing for Abstraction at the RWA Drawing School and at Pegasus Art in Stroud.
Materials are provided in the cost of the workshop and anything special that is required is listed beforehand. The workshops are usually whole days from 10-4 or they are over two days at the weekend.
Usually I find that I learn more from the students that I teach, so it's a lot of fun, and everyone works very hard.
