I often have "assistance" in the studio. My youngest son is most interested in polymer clay. He seems to understand that it can be almost whatever you want it to be and sees it as the first solution to every creative urge .
I've started buying him his own clay after he came to me one day and said "oh by the way, I used all of the Premo black...does that matter?"
This was his idea. I helped work out the kinks.
