A Trestleboard was an instrument made use of by Operative Master Masons to detail the daily work of the Craftsman. The plans and designs for the work was scratched or carved into or drawn on the surface of the board. The earliest Trestleboard (or more accurately Tracing Board), was thought to have been a wooden board covered in wax. The designs were cut or carved into the wax. The wax could be scraped off and renewed as needed. A modern day Trestleboard in Operative vocations is the Blueprint.
