The second is from a stump in my neighbors yard. I went to ask them about scraping lichen and fungi from their woodpile and they helped me pull these off one of their tree stumps in.
Now I am souring the fabric in hot water with soda ash and alum. I will let these soak all night and then hand to dry, before dyeing them. I will be testing with the following ingredients added to the dye: salt, vinegar, lemon juice, alum, cream of tartar, ammonia. Can't wait to try this. Will work outside with old pots and the heat base for the turkey fryer.
