Quick Answer
To make a length of cordage, about 5-10% of bark is typically needed, which translates to around 1-2 strips per branch, with each strip being about 1/4 inch wide and 1/2 inch long. The required amount of bark depends on the thickness of the bark and the desired cordage strength.
Selecting Suitable Bark
When searching for suitable bark for cordage, look for branches with a moderate diameter, ideally between 1/2 and 1 inch in thickness. This size range provides the optimal balance between bark thickness and branch strength. For each branch, strip the bark from both sides, working from the base towards the tip, to avoid damaging the underlying wood.
Stripping and Preparing the Bark
To strip the bark, use a sharp knife or a stone tool with a curved edge. Hold the branch firmly and shave the bark off in thin strips, working in a consistent manner to avoid tearing the bark. Once you have the desired amount of bark, clean and flatten it by folding it in half and running a stone tool along the crease. This helps remove any remaining wood fibers and excess sap.
Spinning the Cordage
To create the cordage, hold two strips of bark in each hand, overlapping them slightly. Begin to twist the strips together, using a consistent motion to tighten the fibers. As you twist, the bark will start to bond together, forming a solid cord. Continue twisting until you reach the desired length and thickness of your cord. You can test the cordage strength by pulling on it gently – a well-made cord should be able to withstand moderate tension.
