Earlier this week I shared some dye results using red cabbage. Yesterday I was revisiting it, hoping to recreate the lovely darker blue color, and hoping to remember exactly how I got it in the first place.
Thankfully I was able to remember which tricks I used, and came up with a shade that was close to what I was looking for. And I've written it down now.
The silk looked so lovely flying against a patch of (short-lived) blue sky.
It's funny how the dye color starts off purple, but with the addition of a tiny bit of ammonia, turns to blue. A sprinkle of alum, and you can turn the blue back to purple.
Given the chance, I prefer to dye with red cabbage outdoors. It gets a little rank, especially if you add in the ammonia. I don't particularly like using ammonia but it does help with both the color development and the colorfastness.
The beautiful pale blues came from an exhaust batch, and for grins I threw in a piece of unbleached cotton drop cloth. It looks a lot like chambray denim and I have a little project in mind for it. If it mellows towards a grey color like my other red cabbage projects have, I think it will look especially nice.
I'd love to be able to teach classes on dyeing someday. Anyone want to come out and play? It's fun stuff.
Have a great start to your weekend, everyone!
