Definition: Parchment is a paper-like material made from sheep or goat skin. Very fine parchment is called Vellum and is made from calf skin. Parchment is not paper, as technically, paper is made from cellulose pulp.
The reverse side of parchment paper has a pitted texture from the hair follicles in the skin, but the drawing surface, on the carefully prepared underside of the skin, is extremely smooth. The flawless surface of parchment allows a very fine line, making it ideal for drawing and calligraphy.
If you're suddenly feeling squeamish about your Pergamano parchment craft, don't worry - Pergamano parchment is not parchment but an imitation made from treated cotton/wood pulp.
Also Known As: vellum, goatskin paper
