i just finished teaching another beginners mold making and concrete/fiberglass casting class with the washington glass school
I always worry that the students learned enough. each time i teach i get a better sense of that and learn small ways to improve the class for the next time.
i havent offered an advanced mold making class yet, but i think i'll start working on it. Bringing in the addition of brush on molds, two/three part molds, and mother molds will be an exciting class. My main problem with trying to figure it out is how to cost out materials for an unknown project. i'll work on it.
