WORKSHOP Natural dyeing with indigo, madder, weld, genista, reseda, cochineal, walnut, catechu, logwood. For many shades of the rainbow. And combinations of these dyes with shibori technique. On silk, wool, cotton, linen and/or hemp.

In this 3day class we are going to submerge ourselves into dyeing and over dyeing with shibori or without in search of abstract colour beauty. We will discover the many possibilities of these rich natural dyes on well prepared fabrics. We will work with pre-mordanted fabrics.


We will use part of the dyes as extracts. But the additives and process specifications you will be learning are equally suitable for these dyes in more rudimentary form. We will work with : madder, cochineal, indigo, genista, reseda, walnut, cutch en campeche wood.

We will make also make combinations of these dyes. For those who want to with shibori using plastic, inner tube or string and if you bring clamps. Just over-dyeing without tie-dye can also be satisfying.


We will have the time to learn in depth and be given handouts about the best way of mordant, preparing your fabrics before dyeing. For each type of fiber that we are working with here. Which is silk, linen, hemp, cotton and wool. Together we will make colour samples to be divided.


You will also be challenged to make your own experiments in making combinations and getting all kind of shades. You can bring some of your own premordanted fabrics and eco-printed samples to make color tests.
