An easy-to-use kit that can be re-heated as you need it. Contains all ingredients to make a dark indigo blue colour; instructions included. Will dye 1kg of fibre.
Suggestion: If dyeing small quantities of fibre/fabric/yarn then try using an old slow cooker, for dye use only, to be able to store and re-heat the vat when required.
