I finally got a yellow on the quills. So being inspired this afternoon I'm going to dye some quills with indigo and overdye with the Osage, to see if I can get a green or teal color. The replacement batch of quills is working wonderfully.
Quills have an almost magical property to them. You can pull quills out of the same exact location on a hide and the quills for one side will dye beautifully, the quills from the other side dyes marginally - if they take color at all. I have about 5 ounce of quills that flat out refused to take any dye at all. So I need to come up with a project that uses a lot of white quills1
Now to figure out how to store these once sorted by size.
