Step 2: Prep the base layers
Cut out three pieces of the cork shelf liner. I think 2 layers would have worked also. The more layers, the stiffer it gets.
Cut out a corresponding piece of the plastic mesh to use as the grid look top layer.
From the aluminum duct repair tape, cut out strips that will be the conducting traces under the grid. Mine were about 3/8ths inch wide.
Peel the backing paper away from the cork pieces.
Laminate together leaving the adhesive side up. This will be your working surface to attach the traces and the covering grid.
Laminating the pieces helps take out the curl from the roll.
