My Tennessee studio is surrounded by trees. Among the rows of trees an old persimmon tree laid dead after years of providing fruits. I noticed that after a heavy season of rain the bark had been lifted and dried in this position. I carefully peeled a piece off and transported it to my studio in New York City. The rest is a trade secret :)
Old folklore says that a persimmon seed cut in half can predict the winter conditions. A spoon shaped seed predicts snow. A knife shaped seed predicts bitter cold and a fork shape seed means a light dusting of snow will fall..
