Indigo Dyeing

What is indigo? 

Indigo dye is an organic compound derived from indigo plants that is typically used to dye cotton to produce a destinctive blue color. The Indigofera tinctoria variety of Indigo is among the oldest dyes to be used for textile dyeing and printing and has a rich history. It was domesticated in India - which was the earliest major center for its production and processing. Many Asian countries, such as India, China, Japan and South East Asian nations have used indigo as a dye (particularly silk dye) for centuries. Indigo made its way to the Greeks and the Romans, where it was valued as a luxury product because blue dyes were once rare. Nearly all of the indigo dye nowadays is synthetic, especially the dyes used to produce blue jeans. Our team was lucky to have the opportunity to learn about and experience first hand the art of natural dyeing using organic sustainably-harvested indigo extracts with textile expert Kristine from A Verb for Keeping Warm.

The indigo that Kristine works with was grown in Laguanitas, which is located in Marin County. It was dried and then composted on a special floor in January of 2012.

The indigo is stirred every morning and night. The smell is unmistakable, similar to a mixture of cheese, latrine, and manure.

Using various folds and objects such as clothespins and wood blocks, we create spaces difficult for the dye to reach.

 Melissa was a natural pro at dyeing and set a trend with her "block print" by using clothespins.

Working in one minute increments, Lauren brings her piece up to expose the dye to air. Oxidation sets the indigo into the fabric. The more repetitions, the deeper the color.
