Wood carving, as well as stone carving, is another of the greatest artistic expressions of the ancient Maya. Today, artisans work sustainably with native woods from the jungle in the Calakmul Biosphere Reserve in Campeche. As part of their preparation process, the woods undergo a long drying process before being worked and turned into unique pieces. The weaving of jipijapa, a native plant from the tropical areas of the American continent, began to appear in Campeche around the year 1800. Artisans collect the jipi to prepare its fibers to obtain different thicknesses. This fiber is woven in a humid environment and the process depends on the fineness of the weave, which can take from a week to a month.
