A hook put in the wall at the top of the cast may be fastened into the wire eye, usually provided in such objects, to insure greater security. It is sometimes desirable where the relief is deep and heavy, as in the case of some of the gothic figures, to provide a small wooden base to hide the mechanism which holds the cast in place, and to give a greater appearance of stability. The simplest kind of mouldings are the most successful, and the fewer the members in this base, the less conspicuous it is and the easier to keep clean.
