A great project idea for classes, camps and youth groups! Students can design on any polyester or cotton fabric. Saturate the cloth with ink, then allow it to dry. Colored artwork is permanent and completely washable after heat-setting. Try these markers on T-shirts, tote bags, cloth napkins & placemats, hats and much more. 80 Fine Line Marker Class Pack includes 10 colors: black, blue, gray, lavender, lime, orange, pink, red, teal and yellow. AP Seal, non-toxic.
