The individual parts of each artwork began as models for industrial castings.  From blueprint specifications, a patternmaker built the model of hardwood, usually mahogany or maple.  The wood model or pattern was used to form a mold in a sandy substance.  Liquid metal was then poured into the mold to form the castings. 

Once the mold and castings were made, the wood pattern was discarded, and the metal castings became part of a machine, aircraft, auto or some other useful or decorative object.  Most metal things we see or use were originally made from a wood pattern. Some of the patterns in these artworks are 70 years old, dating from World War II aircraft parts.  Others are models for recent castings for parts of street lamps, machines, automobiles, or new planes and rockets.

This artist collects discarded wood patterns or models, strips off the original finish, and refinishes them.  She then studies the shapes and sizes of one or more patterns, often makes new geometric wooden pieces to compliment the patterns, and arranges them all on a plywood background.  Once a balanced and pleasing composition is created, she plans the color scheme and paints each pattern, fastens it to the plywood background, and attaches a hanging system to the background board.
