Once upon a time, my young granddaughter used clay to express herself. I taught ceramics a few years ago, and still have kilns, and I know about clay, so we worked together to enable her expressions to become cone 5 glazed ceramic art. Her self-chosen theme animal was Tatanka, including the white spirit Tatanka that she dreamed about from time to time. Tatanka still roams my small ceramic studio through images tacked to walls. I sometimes notice Tatanka rushing at me when I am about to waste time. Thank you, Tatanka.
