I've always wanted to dye with natural indigo. There is something magic about the way the rich blue colour is created by the oxygenation of the dye. What starts as yellow/green in the dye bath quickly turns blue when touched by air. So, when a friend requested the use of my yard for his indigo kit, I said "Yes!" Turns out indigo is a great party activity - the excitement of the colour change somehow summoned Dionysus and corks started flying. Sedate folding patterns gave way to tie dye and experimentation. Although the results were not as successful as the event, the experience left me wanting to try again and perhaps gather up some walnut husks for another event .... Perhaps Hades will show up.
