Making a rope is not an easy task. To make a rope the way Vikings did about a thousand years ago is even harder.
First, you need to find the right tree. You should then remove the bark at the appropriate time. Then, you have to drop the crust into the sea for three to four months before you can start turning it into a rope.
After all this soaking in the water, the bark can be divided into layers and has become much softer.
The Norwegian creator of the video below With Ensby says:
Cord maker Sarah Sjøgreen makes a traditional three-strand carrying rope. The bark is naturally waterproof, and rots much more slowly than other materials used to make ropes.
This explains why an intact rope has been found in Viking things dating back to 800 AD.
