We already asked Audrey Louise Reynolds to show you how to dye of natural causes and turn boring cotton into composted masterpieces, but in case our video wasn't clear enough, Etro's given step-by-step instructions on how to bake one of their classic white oxfords into a blueberry beauty. We assume they have a no refunds policy in case you screw up, but if you're courageous, check out each step after the jump, and go to their website for even more guides on dyeing with other edibles like coffee and salt.
