Jacquard Procion MX Dye
Procion MX is one of the most vivid, cold water fiber reactive dyes available for cellulose fibers (fibers from plants such as cotton, linen, sisal and rayon). You can easily create a range of colors from pastels to deep jewel tones. Perfect for tie dye, you can also easily use Procion MX dyes in the washing machine and with many other techniques. Colorfast, permanent and washable- This is the only dye that will fix without heat! All you need is soda ash to set the dye.
One 2/3 oz (19g) bottle will dye more than 1 lb (450g) of dry fabric. (Very bright colors will require more dye and pastel colors will require less.)
