With this Pentel PTS15 textile chalk you can make waxy drawings on cotton. This set contains 15 colours so you can create unique, colourful designs on your clothes or accessories. The textile chalk works best on light-coloured textiles such as linen, cotton or silk. Make sure you wash the textile before you start working with the Pentel PTS15 chalk. After applying your design, cover the drawing with clean parchment paper. Then iron over it with a heated iron. This way your design will remain permanently on your garment or accessory and the textile can be washed. As long as you do not iron in the textile chalk, your design can be corrected and even completely erased. Ideal when you accidentally made a mistake.
