Hi starseed, I haven’t tried suminagashi myself yet. People use rice paper *which is named as Xuan paper on Inkston. In theory, you can try any Xuan paper on inkston. However if I try, I would like to use sized Shu xuan paper or Wen Zhou pi paper because I like to get more detailed fine lines between colours. Wen Zhou Pi paper is a very strong and flexible paper due to the high percentage of Mulberry fiber.
