The indigo dye powder is weighed and packed in a polythene grip-seal bag. The bag is then labelled and put in a second grip seal bag for extra protection. I then place the indigo dye in a small padded envelope and post it to you First Class.
The Indigo vat uses spectralite and soda ash. Navigate to "Blue Dyes" > "Indigo Dye" for instructions on how to dye with Indigo Dye.
I hope you enjoy achieving beautiful blues with this exciting natural dye.
