ABSTRACT:
A method is provided for making a pattern comprising a metallic outer shell filled with a fill material. The method includes the steps of first forming a pattern of relatively soft material, then forming a shell as, for example, of plastic, around said wood pattern, and then electroplating a layer of metallic material within the shell to form a second shell which is then removed and in some cases filled with a fill material to provide the final pattern.
