dear Bob, Carve your own! Rio and other suppliers sell blocks of
wax and tubes which you slice to make rings. An x-acto or
frisket knife available in art supply stores, possibly a wax
file from Rio or another jewelry supplier some 400 sandpaper and
a piece of pantyhose for final finishing are all you need.
"Modelling in Wax for Jewelry and Sculpture " by Lawrence
Kallenberg is an excellent book on the subject. If the wax
breaks, glue it with krazy glue. Have Fun! Pat
