Hello May,
Thank you for your comments.
My use of green persimmons comes from what I think I understand from Korean dyers of the Jeju islands.
I posted a brief update to
https://quilterscomfort.blogspot.com. I will assemble a persimmon web resource list from my searches. I have mostly been working with the green persimmon. I cover them with “set out water” to process. I have purchased some kakishibu ferment to compare with the fresh when used on paper. There is a lacquer like finish. Fresh green persimmon can give a hard, lacquer like finish too. I have saturated multiple times two canvas bags, leaving them to soak overnight and now dry, each has a hardened surface. I do find it interesting that the persimmon really develops one side on fabrics. I also have bamboo socks and some fabrics with hard coatings. I need to check the persimmon I put to ferment last year. When I last checked in mid winter, all of the jars had “a mother”, like in vinegar. I put some of the liquid to fabric and color came easily when sun dried. I need to strain and rebottle as soon as possible.
