The term 'It's a Dyeing Art' is referring to the traditional Indonesian art of BATIK. BATIK is a method of wax-resist dyeing applied to cloth, which is used to create intricate designs. The technique involves using hot wax to draw patterns on fabric, and then dyeing the fabric in different colors. The wax prevents the dye from penetrating the fabric, creating a unique pattern. BATIK is an ancient art form that has been practiced for centuries in Indonesia, and is now popular around the world.
