I do love indigo and I'll likely find further reasons to do dye batches of one kind or another. Between the "developing" effect of the dye when it hits oxygen and the stunningly deep, organic blues, it's really hard to beat real indigo. Somewhat endangered, imagine that another heirloom technology, it's still fairly easy to obtain. Something, I think ought to be taught in schools, it'd make a fantastic chemistry project, art or home economics; not to mention History (note the capital H).
The next thing I'd really like to approach is woad, another ancient plant dye. I've found the materials but it looks to be a bit more complex than indigo and certainly more so than something like Rit dye that can simply be mixed in a bucket or washing machine without a lot of fuss.
This batch of scarves will be up in the Susan Howell gallery at 1987 Hyde St in Russian hill for another month or so and then I'll either find them homes in a little more personal way or put them up on Etsy, who knows?
If anyone is of a mind, let me know and I'll run an indigo workshop where we can explore the dye itself as well as basic shibori.
