As an alternative, for indigo and woad dyeing you may wish to try the fermentation vat method. It requires a little more patience but can be succcessfully used in indigo and woad vat dyeing by using different products to achieve the necessary oxygen-reduction for the vat.

For this method you will need calcium hydroxide and fructose. We can supply simple instructions for this method with your order.

We apologise for the inconvenience.
