Batik is both an art and a craft, which is becoming more popular and well known in the West as a wonderfully creative medium. The art of decorating cloth in this way, using wax and dye, has been practised for centuries. In Java, Indonesia, batik is part of an ancient tradition, and some of the finest batik cloth in the world is still made there. The word batik originates from the Javanese tik and means to dot.
