Dr. Ph. Martin's Spectralite is an excellent paint for marbling & airbrushing. It leaves no 'feel' at all on silk and gives knock-out colors. Can be used on paper, fabric, leather, film, just about anything. It has more pigment than other paints so it covers better and faster. Water-based, non-toxic, and very fast drying. Used with a catalyst on fabric that will be washed.
