I have found my copy machine to be useful when designing. I draw a
top, frontal and side view, copy it and then glue to the wax using
spray on adhesive. The design can be copied again and mounted on thin
cardboard and cut along specific lines to male a template. The
template can be used to get dimensions correct during the carving
operation. Lastly, the design can be precisely enlarged or diminished to
make companion pieces.
