Check out my Sept/ Oct PMI article "Elevating Earthenware"
I recently had an article published in Pottery Making Illustrated about my method of building and decorating. The article "Elevating Earthenware" highlights surface decoration techniques that can help build depth at cone 04 with slips and glazes. It also shows the foam/cloth mold technique that I developed while I was in Florida. I haven't actually seen the article yet so let me know how it looks if your a subscriber.
These images below show a close up of the molds in action.
