Quick Answer
To document your dogbane collection and processing, keep a detailed log of the date, location, and quantity of the plant material collected, along with notes on the processing methods used, such as drying and retting. Include photographs or drawings to illustrate the different stages of processing. Consider measuring the strength and durability of the final cordage.
Collecting and Drying Dogbane
When collecting dogbane, focus on areas with high concentrations of the plant, such as along streams or in moist meadows. Use a pair of scissors or pruning shears to cut the stems, avoiding damage to the surrounding vegetation. Remove any leaves and debris from the cut stems, then bundle them together and hang them upside down in a dry, well-ventilated area. The ideal drying temperature is between 60°F and 80°F (15°C and 27°C), and the stems should be kept away from direct sunlight. Aim for a moisture content of 10-15% by weight, which can be achieved by drying the stems for 1-2 weeks.
Retting and Processing Dogbane
Once the stems are dry, they can be retted by soaking them in water for 1-3 days. This process breaks down the pectins that hold the fibers together, making it easier to separate them from the rest of the plant material. Use a retting solution of 1 part water to 1 part vinegar to help soften the fibers. After retting, use your hands or a processing tool to separate the fibers from the remaining plant material. Sort the fibers by length and quality, then card or brush them to align the fibers and remove any impurities.
