Vellum (derived from the Latin word vitulinum meaning made from calf, leading to Old French vÃ©lin, calfskin) often refers to a parchment made from calf skin, as opposed to that from other animals. It is prepared for writing or printing on, to produce single pages, scrolls, codices or books.
A modern imitation is made out of cotton. Known as paper vellum, this material is considerably cheaper than animal vellum and can be found in most art and drafting supply stores. Usually translucent, paper vellum is often used in applications where tracing is required, such as architectural plans.
