1) Draw the design2) Transfer the design on to the
veneer using carbon paper3) Cut out the shape and remove4) Place the space over another
piece of veneer lining up the grain
5) Cut through the gap or ‘window’ to the veneer below. Tape the cut-out piece into the gap
6) Build up the picture and add a frame

3) Cut through both veneer layers at the same time
4) The veneers are then interchanged and taped together
5) Glue the veneers to the background
