Natural Dyeing with Cutch
Earthen, tawny umbers are the stuff Cutch is made of. If you're looking for hues that are made to represent the mystical world underfoot, Cutch will likely fit the scene perfectly.
Cutch is derived from the heartwood of the Acacia catechu tree. It's rich in tannins and catechu, which allows it to bond permanently with the addition of a mordant. And its syrupy, almost coffee-esque aroma is the definition of earthy goodness.
It is actually not the tree itself that is used for dyeing, but instead, an extract derived from soaking parts of the tree in hot water till a thick substance forms. It is then dried and pulverized to a powder consistency.
Cutch, in this case, is used as a textile dye, but has a long history of use in preserving fibers and tanning animal hides. It's also commonly used in Ayurvedic medicine, and in foods and drinks.
Cutch is a substantive dye, and although it is rich in tannin, using a mordant will dramatically increase its wash, rinse and light-fastness.
NATURAL DYE TIP
I recommend diluting the Cutch dye powder in a small quantity of water (warm or hot is fine) before adding it to the dye bath. It will be much easier to thoroughly and efficiently mix in this way.
HOW MUCH TO USE
A little Cutch will go a long way. 20 grams will dye a varied quantity of items, dependent on the weight of those items and what shade of color you are looking for (dark, medium, lighter tones).
To achieve a rich, dark color, use approx. 1:2 to 1:1 (weight of Cutch : weight of Dry Fabric). For lighter shades, use less dye.
