Here is my sure fire recipe for a mini indigo vat. This is ideal to dye a T shirt or two.
Believe me, the feeling of exhilaration that you will have when you see that shade of blue after your 5th dip is priceless!
I'll add bits as I go.
15 grams Indigo pigment powder
350 grams overripe bananas
Utensils and other materials:
A container of about 2.5 quarts with a lid. I recoup plastic buckets in which my husband buys his chocolate powder!
A sieve like the one pictured on the right. These are available at Target. The great thing about them is that they open out to fit various sizes of pots.
