You can use virtually anything as a mould - pottery, china, glass, plastic or metal. Anything that is non absorbent in fact. You can paste straight onto the items and provided you have used a release agent (see "Getting Started" http://www.papiermache.co.uk/exec/cms-d … iew/id-23/ ) you should have no trouble removing the papier mache form from the mould once it is completely dry.
