I let the forms harden somewhat and we carved when they were semi- moist.
Meanwhile, we studied Henry Moore's work. They did well and did not break small
parts even when making "holes" through the forms. We stored them in zip-lock
bags until we were finished with the forms. Then we let them air dry.

here's a tip: Add used coffee grounds to the plaster when mixing. It takes on
a tan color and looks like stone with the little flecks of brown. We sealed
them with gloss acrylic medium.

 We fooled everyone. They thought we carved in stone!
