When you dye your own fabric, you can of course use the dyepowders as they are sold by the companies. Mixing dyepowders yourself is fun and gives sometimes surprising results. This picture shown fabric on which I used a combination of G&K nickel 603 and Dharma marigold 67. The nickel is gradated with 50% water with each f8 and 7,5 cc of marigold was added to each baggy. I had expected a much more greenish fabric but instead I got these lovely colors.
