3 day Clay Plaster Workshop September 14-16 in Vacaville, CA 

Come learn about Clay Plaster at this 3 day workshop where we will apply clay plasters on a small straw bale farm building under construction at Soul Food Farm. Soul Food Farm is a woman run farm that produces organic olive oil, lavender oil, flowers, and eggs.

In this workshop, we will be using the native clay soil as a base material for the plaster. Participants will get hands on experience through all stages of the plastering on the building. We will mix and apply the scratch coat, the brown coat and the finish coat. We will have the opportunity  to try relief plaster and ornamentation.

The goal of the workshop is to  provide a broad experience to beginning plasterers. A mix of instruction time, hands on experience along with a handout will provide you with the basic knowledge of straw bale building and plasters.. Evenings will allow for  photo presentations and additional question/answer time.


The plastering instructors are Yoshi Makino and Kathy Gregor. Yoshi is a professional plasterer with many years of natural plastering under her belt. Kathy is an experienced finish plasterer with a talent for plaster ornamentation.
