My second graders made pinch pot monsters. 
First, they created pinch pots with clay. Then students added eyes, mouths, and other details to create a monster.  All added pieces were scored and slip.  Hint: If you add vinegar to the slip, it attaches better.After they were out of the kiln, we painted with watercolors. I then put a clear acrylic sealer over it, to add a shine.
