This 2.25 ounce jar of Ecru Dye-Na-Flow is a super saturated, highly transparent fluid acrylic paint that is permanent on any porous or semi-porous surface. Simulating a true dye in many ways it can be used on natural and synthetic fibers spreading on fabric until it is thoroughly absorbed, sinking into the threads. Color is intense, washfast and will not change the feel of the fabric. Dye-Na-Flow is extremely versatile and may be used on an array of surfaces including wood, paper, clay, canvas, suede and more. Use for multiple types of applications too!
