My indigo vat has been languishing in the bucket over the past 2 months. It was completely oxidized, but I have instructions for reviving it, so I spent a day adding chemicals - waiting - adding more - waiting - and viola! It came back to life! What fun!
It changed from a dull murky puddle to this - yellow-green liquid beneath a coppery blue surface, with a nice bubbly "flower" floating on top!
I wanted to try starting with some MX dyed fabrics - I chose these yellow and pink pieces - hoping for results more in the greenish or purplish range.
