Wood Adult Session 3B: Carving a Relief Panel (4-week) WED (May 28 - Jun 18) • MAIN
with Julia German

This course could be a 4 week course as well, or even a two day class. Depending on the length of the class, I'd just prep more of the pieces we would start with in advance. The idea would be to create a carved decorative panel that could be used as a crossover piece with another shop. It could be a book cover for paper projects that could overlap with printmaking. It could be a door on a metal box. It could simply be a hung piece of 2D art. It could integrate wood burning, or be integrated into another woodworking project as well. Since it could become a panel on a sculptural metal or ceramic piece, depending on these other studios, it could really be anything.
