Rit Powder Dye works beautifully on many washable fabrics including: Natural fibers, such as cotton, silk, and linen. Synthetics such as rayon, nylon, and acetate blends will tint evenly but will not achieve full color. For maximum coverage, use the washing machine technique. Use the stove-top technique for best color results when dyeing with Black dye or other dark colors.
Great for tie-dye techniques, and you can brush or rub it on wood projects for staining or stenciling.
