Yesterday I worked on several bowls, a great horned owl, a black bear, and two swallows. First I make a drawing of my choice on the clay. Then I fill in the subject with stained slip. I wait for the slip to dry over night and the next day I use my sgraffito tool to remove the slip in short and long strokes to reveal more detail. I use a soft dry brush to remove the pieces of clay I sgraffito. Here's the great horned owl.
This is what the owl looks like before using the sgraffito technique.
