Several layers of papyrus leaves were laid in different directions (usually perpendicularly) and pressed together while wet. The surface that was written on (only one side of the paper was used) was treated with glue sizing so that the ink wouldn't bleed.
In a dry climate, such as Egypt, papyrus is stable, but storage in humid conditions will result in molding.
Papyrus is occasionally used for artwork, but watermedia can cause the papyrus to buckle.
A Computer Font is also named Papyrus.
