"I'm so glad I invested in this course! It's really the best of both worlds: extremely detailed hands-on guidance to see and feel how the materials behave, and better information than in most books because it's grounded in real experience. I look forward to consulting these videos again and again in my earth building journey."   Rebecca, clay plasterer in Australia.
The Art and Craft of Earthen Finishes
Earth plaster is one of the most satisfying, useful and beautiful things I've ever learned to master. It opens up a world of construction, artistic and decorative opportunities. Once you master this ancient craft, you can not only render houses, you can create gorgeous, textured interiors, create niches and alcoves, make earthen structures like cob ovens, sculpt reliefs, make wall mosaics, and so much more. Your imagination is the limit.

I'm not going to lie though. Earthen plasters can be tricky at the outset. It's an artisan skill. Recipes often don't work because clay plaster is notoriously dependent on local climate, soil make up, and the surface you want to render.

This Perfect Earth Plaster Course will teach you step by step how to create plaster just about anywhere. It empowers you by giving you the tools and understanding to become a plaster master yourself with some practice. In this course, I share with you a raft of personal techniques and discoveries too.
"Very informative and good instructions in the text and videos! Absolutely helpful, thanks for putting it together." Nanda Doornik, cob oven builder in Ireland.
