This highly saturated, highly transparent fluid acrylic paint is permanent on any porous or semi porous surface, including natural and synthetic fabrics, and in many ways stimulates a true dye. The colours are intense, washfast and will not change the feel of the fabric. Dye Na Flow is versatile and may be used for many diverse applications, from silk painting to wood staining. Use on natural and synthetic fibres, wood, paper, clay, canvas, suede, leather and more.
