All purpose concentrated. The quick, easy way to bring fresh color to fabrics and more! Packaged color reflects approximate results when dyeing white or off-white 100% cotton using the washing machine technique (RIT black dye reflects stove top technique). Use RIT color remover to remove original fabric color before dyeing to a lighter or completely different color. One package dyes 1 lb dry weight about 3 yards medium weight fabric to a light or medium color. (Example: pants/jeans or blouse/ T shirt or 1 pair curtains). Use Rit fabric treatments for your special fabric care needs.
