That is neat but I bet it is a lot of work. I recently saw a video on youtube of some S American natives making cordage. They were using a yucca type plant but the leaves were much longer. The woman pulled each leaf through some type of thresher to separate the fibers and remove the excess material. Then they soaked it and had a cord making party.
I’ve always wanted to try making a string from squirrel hides. I hear they make tough, long lasting strings. It takes 2 squirrel hides to make 1 string.
