(8) How is amatl (amate) related to papel picado?
In addition to painting amate, the Aztecs also cut silhouettes from the paper with obsidian knives. The resulting figures were primarily ceremonial in nature. Aztec gods and goddesses were cut out. Very few Aztec examples survived to today, but artists prize amate which was made in the traditional method. These early cuttings with obsidian knives are the inception of the papel picado seen today (Miliorn).
