Yet another day papier mache-ing (Jessie, who worked with us last year on the horse, is back, adding layers to the arms and head!)
New knowledge: Not only does papier mache shrink when it dries, but as it shrinks over styrofoam, certain parts of the foam compress whereas others do not do so as much, so the arms that I so lovingly carved into nice rounded shapes have morphed back into to blocky shapes. They will look fine on the puppet but are not how I envisioned them.
