The easiest way for me to gain instant popularity is to announce a "free day" for clay. I'm always impressed by what the students come up with. Louis made this whole delicious spread.
Sarah and Abbie had a particularly brilliant and generous idea. They made several different cakes and cut them into enough pieces for each student in the class to take one home (after I baked them of course). It was their own miniature bake shop!
