Dharma used a simple recipe to get these great colors with our
natural dyes so
you can have a reference for the colors they will give.
Keep in mind there are many recipes and mordants that will yield a wide range
of colors and shades from each dye material, so consult a natural dye book for
more on this. We carry
The Craft of Natural Dyeing by Jenny Dean.
For the deepest colors, use a ratio of 1 to 1 dyestuff to fabric, or 2 oz dye
to 2 oz fabric, but you can still get good colors using much less dye. We used
about 3-4 tablespoons per yard of fabric. Cochineal is an exception as it is
very concentrated, so use only about a 20% ratio. The dyebaths can be re-used
to get lighter shades. Experimentation is the best way to determine the right
amount of dye for the type of fabric you are using and the color. We found the
silk and velvet absorbed the colors the deepest. Some cottons will yield
different and deeper shades using Tara Powder (a form of tannic acid) as a
mordant with soda ash as an assist.
Yellows can be overdyed with indigo to get shades of green, and reds overdyed
with indigo will give purples.
The Method:
1. Prewash your fabric with
synthrapol, rinse well.
2. To mordant the fabric (or yarn) simmer together with 2 teaspoons
Alum and
1 teaspoon Cream of Tartar per yard of fabric for 1 hour. Allow the fabric
to cool in the solution. Squeeze out excess water from material. Rinse and discard solution. (all the alum will be
absorbed by the fabric)You can allow the fabric to dry if you want to stockpile some pre-mordanted material, but you want to use it in about a month as over time the alum can degrade the fabric.
3. Measure and simmer your dyestuff for an hour using enough water so your
fabric can move freely, allow to cool.You may need to chop up larger roots, such as when you use madder. Roots also like to be soaked overnight for some of the darkest shades.This is best done before you mordant or at the same time.
4. Strain out any roots, shavings, etc.
5. Add wet fabric and simmer for an hour, allow to cool in dyebath for
maximum color absorption. Be sure to stir periodically for even dyeing,
turning fabric frequently while simmering. You can save and re-use the dyebath for
lighter shades.
6. Give the fabric a final gentle wash with
synthrapol and rinse.
