what was vellum originally made from?
Parchment is a writing material made from specially prepared untanned skins of animalsâprimarily sheep, calves, and goats. It has been used as a writing medium for over two millennia. Vellum is a finer quality parchment made from the skins of kids, lambs, and young calves. It may be called animal membrane by libraries and museums that wish to avoid distinguishing between parchment and the more restricted term vellum (see below).
