I soaked one piece of cotton and one hank of embroidery floss in milk and water for each batch to see if it made a difference. All of the fiber is mordanted but milk supposedly acts as a binder and I wanted to run a little, unscientific test. I think it made a difference. The darker pieces are the milk soaked ones. Really specifically, it was a little milk and mostly water.
The wool is overdyed, I used the batch I had solar dyed with Curly Dock seeds. It’s so vibrant!!
