Batik is a dyeing technique using wax resist. The term is also used to describe patterned textiles created with that technique. Batik is made by drawing or stamping wax on a cloth to prevent colour absorption during the dyeing process. This creates a patterned negative when the wax is removed from the dyed cloth. Artisans may create intricate coloured patterns with multiple cycles of wax application and dyeing. Patterns and motifs vary widely even within countries.
