focus on producing and applying natural dyes


Have you ever wondered how such exquisite natural dyes are produced in Japan and how they are used? Would you like to make your own natural dyes for use on silks as well as cottons and other fibers? Well be covering all this and more.
This course includes a history of the use and production of natural dyes in Japan along with several projects geared to lead you through this satisfying process. Well be making and using natural dyes in both pigment and juice forms, focusing primarily on cold and direct application techniques. Well cover using mordants vs soymilk to assist colors and how to effectively combine natural pigments with other natural dyes for the greatest impact.
  John will be relying on his fifty years of experience working with Japanese dye methods, drawing heavily on his large library of rare and limited-edition Japanese reference material  - distilling out the most applicable to our modern world.
Spanning four days will allow you time to try out the techniques we cover in class between sessions. Well have an extra session on Saturday, March 15, to review all the information covered in class, answer any questions that may have come up while working on your own, and send you off confident in your ability to create wonderous colors from the materials around you.
