Pouncing

It is similar to tracing, and is useful for creating copies of a sketch outline to produce finished works.

Pouncing has been a common technique for centuries, used to create copies of portraits and other works that would be finished as oil paintings, engravings, and so on.

This pounced drawing made of pricked holes is laid over a new working surface.

A powder such as chalk, graphite or pastel is forced through the holes to leave an outline on the working surface below, thus transferring the image.

The powder is applied by being placed into a small bag of thin fabric such as cheesecloth, then dabbed onto the pricked holes of the pounced drawing.
