I also highly recommend it for maquettes. Students can get an idea of how
that process goes for the sculptor too.
Another interesting thing to do with WetSet, add pieces of mirror or other
found objects to the piece. Because it doesn't need heating and doesn't
shrink, you can really add a variety of "stuff."
Not to beat a not yet dead horse, I also have used WetSet as a flat
drawing surface and for tiles to develop a larger composition.
