After pouring in the vinegar and letting the wool set for about fifteen minutes, I started bailing some of the dye water out of the pot. I saved it in jars, so I will have acid dyes ready to go if I need to make more sky wool.
They are now soaking in water. I should have shredded them, according to the books, to release dye color, but I didn't have the heart to shred things so beautiful - so I'm soaking them whole. The water immediately had a very slight yellow tinge, so maybe color can be obtained without destroying them.
