This lesson focuses on the art of batik, emphasizing the use of wax to preserve colors and create designs on fabrics such as cotton or silk. Essential materials and tools include a Tjanting tool, iron, stirrer, wax pot, dyes or acrylic paint, rubber gloves, and a fabric of choice. By the end of the process, the wax outlines the design, allowing for vibrant colors to remain, particularly in detailed areas like the base of butterfly wings.
