I have not found any recipes for dyeing wool with haskap. I have a couple of books on fibre dyeing (Adrosko and Duerr). These do not contain information on dyeing with haskap. But Duerr’s does have a recipe for dyeing with blackberries. Knowing from personal experience how blackberries can stain I decided to use this recipe as a baseline recipe.
Here’s what I did:
(1) Drain Mordanted Wool – After allowing the mordanted wool to cool in the mordanting bath overnight I removed the lid and could smell the strong presence of sulphuric acid (H2(SO4)). I drained the wool. Then I rinsed the wool several times with clean, soft water.
(2) Making Dye Liqueur – Weighing my fabric, I matched that with an equal weight of haskap berries. Berries were covered with water, brought to a boil, then simmered (180F) for 30 minutes. This was then sieved and set to cool.
(3) Dyeing Wool – Once the haskap dyeing liqueur is cool, add premordanted fibre. Fully cover the wool with water. Bring the bath up to a simmer and hold it there for 30 minutes. Remove the dye pot from the heat. Remove the wool and set it aside to drain, wash with a pH-neutral soap, rinse thoroughly, hang to dry.
