Try using slump instead of hump molds, the difference being that a slump is
something you lay a slab of clay in. We use a lot of thrown mold forms or
plaster molds that are empty. As for unusual forms, I use a half of a
basketball which I found in the street and lots of things from the party
place like party box or party city. Look for stuff at garage sales. You
just look at the outside form or the edge it makes. Also those big beach
balls. I used an old tire to make a baptismal bowl once, it says Goodyear
on the underside. I think Christ would have liked that.
