One day, I would muse, I am going to take those skins and make an onion skin dye.
And the time was now.
I gathered my old dye pots and set to boiling the onion skins in water for about an hour. Prior to that I had mordanted my wool with aluminum potassium sulfate, now soaking in a pot of room temperature water. After the dye bath had cooled some what, I strained the onion skins, gently placing the mordanted wool in the dye pot and raised the temp to a simmer for another two hours. There is a time that the dye is spent, but I wanted to make sure the wool would take in as much as the dye as possible because I was hoping for as orange of a color as I could get.
Then the next day I thought I would try putting in another skein of mordanted wool to see if the dyebath was entirely exhausted or not, it came out a very pale orange (not shown in true color, the very pale orange looks cream in some of the photos).
