We have tried: We tried colored chalks on various materials (cotton canvas, velvet velvet, denim, knitwear, sweatpants, satin, softshell) and drew well on all the above fabrics. To make the line smooth and clear when drawing, we recommend that you always draw with well-shredded sharp chalk. The drawn lines disappear under the influence of water (eg with a damp cloth or sponge).
