Lo spolvero

The dry brush technique is one of the oldest methods for transferring a drawing from paper to a new surface without changing the scale The design was finely perforated along every individual outline With a nozzle that is a metallic tube with a tip similar to that of a needle Laid the perforated sheet onto the new support they proceeded to punch corresponding holes With a coarse mesh canvas bag containing charcoal powder so that the position of each individual hole was imprinted on the support The design could then easily be re-drawn and reinforced with brush-applied ink The traces left by the dust were then removed by brushing the surface with a feather duster
