Quick Answer
Yes, you can use dyes from plants to color your cordage, but the process may be unpredictable and can vary depending on the plant and cordage material.
Selecting Dye Plants
When choosing plants for natural dyes, consider those with high tannin or anthocyanin content, as these compounds are responsible for the color. Oak bark, walnut hulls, and pomegranate rinds are good examples. For reds and purples, use plants like madder root, indigo leaves, or pomegranate rinds. Experiment with different plants and ratios to achieve the desired shade and consistency.
Preparing the Dye Plant Material
To extract the dye, boil the plant material in water for 30-60 minutes to release the color. For example, to make a walnut hull dye, boil 1 cup of crushed hulls in 2 quarts of water for 30 minutes. Strain the mixture and discard the solids. Use the resulting dye liquid as is or dilute it with water to achieve the desired intensity.
Applying the Natural Dye to Cordage
Submerge the cordage in the dye liquid and let it steep for several hours or overnight. The longer it steeps, the deeper the color will be. Monitor the color and remove the cordage when it reaches the desired shade. Rinse the cordage in cold water to set the color and allow it to dry. Note that natural dyes may not be as colorfast as synthetic dyes, and the color may fade over time when exposed to sunlight or UV light.
