The woad vat needs sodium dithionite, or a similar reducing agent, plus soda ash and can be used like indigo. Navigate to "Indigo" > "Indigo Dyeing" for instructions on how to dye with woad dye.
The woad 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 woad in a small padded envelope and post it to you First Class.
I hope you enjoy achieving beautiful blues with a dye used for thousands of years.
