Wax is used to create decorative fabric designs in traditional Indonesian batik crafts. To try your hand at this age-old technique, slowly melt wax over gentle heat, then pour it onto old T-shirts, tablecloths, pillowcases, or other fabrics. Let the wax dry completely, and then immerse the material in dye. Because the waxed sections will not take the color, the material will be left with a unique design. To remove the residue after dyeing, cover the waxed sections with several layers of paper towel, and then iron on a warm setting; change the paper towels as needed until the wax is completely removed.
