Why is inner bark often preferred for crafting strong cordage?

Properties of Inner Bark

The inner bark of trees, often referred to as phloem, is a rich source of strong fibers. This layer lies beneath the tree’s outer bark and is composed of bundles of cellulose and lignin, which work together to provide tensile strength and durability. In many tree species, the inner bark can be harvested with minimal damage to the tree.

Techniques for Harvesting Inner Bark

To harvest inner bark, start by removing the outer bark, taking care not to damage the underlying phloem. Using a sharp knife or scraping tool, carefully shave off the inner bark, working from the base of the tree upwards. This will allow you to access a large quantity of fibers with minimal waste. For optimal results, shave the bark in thin strips, typically 1/8 inch (3-4 mm) wide and 1/4 inch (6-8 mm) long.

Preparing Inner Bark Fibers for Cordage

Once you have harvested the inner bark, begin by soaking the fibers in water to rehydrate them. This will make them more pliable and easier to work with. Use your hands or a simple hand tool to break down the fibers into individual strands, taking care not to over-process them. For best results, aim for a strand length of around 6-8 inches (15-20 cm), which will provide a good balance between strength and flexibility.
