Indigo exists in plants that grow all over the world. It is virtually the only blue dye that occurs in nature. With a fascinating history, indigo is equally fascinating to use: the blue color “magically” appears as dipped fabric is exposed to oxygen in the air! This unique property sets indigo apart from every other dye and makes it especially well-suited for patterning techniques. The dye produces a wide range of blues, from a pale sky blue to the deepest navy. Prized by countless cultures for millennia, indigo is still used today for coloring blue jeans. Jacquard’s synthesized indigo is molecularly identical to the naturally occurring dye and comes pre-reduced 60% for unprecedented ease of use. Available in 0.75 oz, 8 oz and 1 lb.
