Teaching to Build Earth Ovens

I am in the process of finishing an ebook on how to teach your own earth oven workshop. I am starting this thread to find out if anyone knows of any similar publication and to find out if there is interest in it. The book covers everything from: host agreement and consultation, materials and tools, teaching the course, baking procedures, and building your own tools. I am interested to hear from both people who have taught classes and people who want to teach.

Thanks for your feedback! Simha Bode
