Besides the ikat dyeing and weaving, we also had some fabric and clay to play with. A slurry of these three ingredients was mixed up.
So the result was pretty light after one dip in the indigo. Of course, the vat could have been weakened by use as well, it was a busy workshop.
So back to the clay. This time with a brush, applying the clay very heavily. So much clay that the fabric curled up as it dried.
Contrast was much better. The indigo did not creep into the design from the other side of the cloth since the clay penetrated better with the brushing technique.
I've enjoyed sharing my experiences with indigo and hope to hear about what you would do if you had a vat of indigo living at your house.
