==Technique== thumb|upright|Cartonnage of Nespanetjerenpere, ca. 945–718 BCE. Linen or papyrus mixed with plaster, pigment, glass, lapis lazuli, 69 11/16 in. (177 cm). Brooklyn Museum, 35.1265. In a technique similar to papier-mâché, scraps of linen or papyrus were stuck together with plaster or resin and used to make mummy cases and masks. It could be molded to the shape of the body, forming a type of shell. After the material dried it could be painted or gilded. The shell could be decorated with geometric shapes, deities, and inscriptions. During the Ptolemaic era, the single shell method was altered to include four to six pieces of cartonnage. There would generally be a mask, pectoral, apron, and foot casing. In certain instances there were two additional pieces used to cover the ribcage and stomach.
