This is a very nice article in the fashion world about indigo dyeing and the very rich lustrous blue that comes from the process. Having had a great opportunity to try indigo dyeing myself, I can only say that it is a wonderful and very fun experience that is virtually impossible to really screw up doing. And as such, can be a great activity for your whole family, even those in your family with horrid physical coordination.
Take a look at this article, however, for some truly breathtaking indigo creations. I think I am going to change my entire wardrobe to this color.
