  Any depressions may need a hole to allow the vacuum to pull the plastic
into the depression. The hold can be pretty small.  A drill can be used to
put holes in the plaster.  Also, know one company that makes their forms by
carving them directly onto rigid urethane foam.  If you are making large
items, that is MUCH lighter to do. I'm not sure if the form is used as is,
or perhaps they first vacuum a thin sheet of plastic over it that stays on
it. (this technique can be used for a lot of items that might not otherwise
release)
