The pen can be trimmed and sharpened periodically during the drawing process, and with proper maintenance can last for many drawing sessions.
The quill pen, my favorite tool for ink drawing, was the standard tool for writing and drawing in Europe until the 19th century. Goose quills, particularly large (at least 10-inch) feathers taken from the edge of the wing, provide the ideal combination of flexibility and strength needed for fluent drawing that will not scratch the surface of the paper. This Instructable is part of a project I completed for the RISD Museum, for which I copied Luca Cambiaso’s drawing Deposition from the Cross (ca. 1570).
