Can You Use Bark Cordage for Fishing Lines?

Choosing the Right Bark

When it comes to using bark for cordage, the type of tree and the thickness of the bark are crucial factors to consider. For example, the bark of the slippery elm (Ulmus rubra) or paper mulberry (Broussonetia papyrifera) is soft, flexible, and relatively easy to strip. On the other hand, the bark of the cedar (Cedrus spp.) or cypress (Taxodium spp.) is harder and more fibrous. If you’re planning to use bark cordage for fishing lines, look for trees with thick, flexible bark that can withstand moisture and repeated use.

Preparing the Bark

To prepare the bark for cordage, start by removing any loose or damaged outer layers. Then, use a sharp knife or a specialized bark stripper to remove thin layers of bark, working from the outside in. You should aim to remove about 1/4 to 1/2 inch (6-13 mm) of bark in total, depending on the thickness of the bark and the desired strength of the cordage. Once you’ve removed the desired amount of bark, cut it into thin strips, about 1/4 inch (6 mm) wide.

Creating the Cordage

To create the cordage, start by twisting two or three strips of bark together, using a consistent twisting motion to create a tight spiral. Continue adding more strips of bark, twisting them together as you go, until you achieve the desired thickness and strength. For fishing lines, you’ll want to aim for a thickness of about 1/8 inch (3 mm) or more. You can also add a waterproofing agent, such as beeswax or plant resin, to help protect the cordage from moisture and extend its lifespan.
