I have been experimenting with some natural dyes. I have done coffee, walnuts, onion peels, etc. I have not needed to work with mordants until now due to the color fastness of these dyes. I had three skeins of merino burning a hole in my yarn closet so I busted them out to get dyed with the onion peels that I have been accumulating for the last month. They are still soaking overnight but here is a picture of the dyes with their respective mordants.
I will post pictures when the yarn is done 🙂
