I post this here as some were interested in this method. I believe @dudewuttheheck bought a Kakishibu belt from Japan. Applied in multiple layers and exposed to sunlight, persimmon gives a really vibrant russet color. I bought the dye from Amazon (Turner Odorless Persimmon Dye). It is pretty dilute, and in one application there is not much color. But apply multiple layers (4 in this picture), expose to sun for a few hours, and you are off to the races! Pretty cool stuff. Kakishibu is an art in Japan, you can buy various fabrics, paper, and even jeans dyed in persimmon. I make my own belts from blanks, and this is certainly a fun project. But it is hell of a lot easier to dye a natural belt than a jacket, particularly if you need to apply four layers. On the picture below, bottom left is uncoated, bottom right is one application, top is four applications plus a few hours of sunlight. Some people in Japan keep it in sunlight for a month!
