Calfskins are thin but tough and flexible, hence they are the traditional choice for binding and manuscripts. Calfskins sometimes exhibit surface veining and often lack a discernable grain. This latter quality, along with a dense skin fiber weave, is ideal for text or calligraphy, as there is less visual competition from the parchment surface. Calfskins average 5–7 square feet and are available with a calligraphy/manuscript-quality finish on one or both sides, or with a standard unfinished surface for binding or interior and furniture applications. Color range includes natural, white, spotted, field (veiny), and transparent.
