Many Indonesian batik patterns are symbolic. Infants are carried in batik slings decorated with symbols designed to bring the child luck, and certain batik designs are reserved for brides and bridegrooms, as well as their families. Batik garments play a central role in certain Javanese rituals, such as the ceremonial casting of royal batik into a volcano. In the Javanese "naloni mitoni" ceremony, the mother-to-be is wrapped in seven layers of batik, wishing her good things. Batik is also prominent in the "tedak siten" ceremony when a child touches the earth for the first time. Specific pattern requirement are often reserved for traditional and ceremonial contexts.
