than the indigo baby by the stove mentioned in an earlier post.
i sort of follow the instructions on the Dharma website but I also use my chemists intuition to some extent when the smell or colour just doesn't seem quite right. I also realize that it is possible to have a negative experience when the indigo you purchase is "stale". This happened the first time I bought indigo but never again since that time. So if you are entering into the blue vat world, don't be discouraged if your first results are not what you expected. Try another supplier and give it another try.
On sunday morning I really sprung forward, waking up with a startle, remembering I had left the indgo vat on the kitchen table to bask in the sun all day. I had visions of indigo dyed cat paws and whiskers and little blue prints all over the house but thank goodness the visions were only in my mind and the vat and the cats were all safe and sound.
