Today I’m pre-mordanting all the yarn with alum for tomorrows dyeing. With 2 kg of yarn it’s probably gonna take the better part of the day to get it all done. But it’s a lazy day so I don’t mind.

I’m using a standard recipe with 20 gram alum to 100 gram wool in 5 liters of water. I heat the alum water to 60 °C and put in the wool. Then I heat the water to 90 °C and let the wool lay there for an hour. The wool will then cool in the water and then dried in the shadow.
