Faith – Carved Wood Sign. 16x29x1. Our carved signs, plaques, and frames start their journey in a design lab. After a design is created in a computer, the wood is transferred to the CNC (Computer Numerically Controlled) carving machines. Operators load the machines with 4ft by 8ft sheets of wood supplied domestically by a lumber mill in Minnesota practicing sustainable timber farming. Once the design is carved, each piece is hand-sanded, hand-finished, and hand-assembled.
