The cross is planed and thickened, sanded on both sides and chamfered, and varnished on the back and sides with a woodworm- and mold-resistant primer and a walnut-colored water-based varnish. The canvas is glued to the board with rabbit-skin glue, prepared with gesso and rabbit-skin glue (80% Bologna, 20% Meudon) in several layers (approximately 10), sanded, and ready to be painted.
The board is approximately 2 cm thick.
