When I was in Boy Scouts we made our own ropes with a hand-made wooden machine with metal hooks. On one end the had 3 hooks, and the other end had one hook. They were clamped to tables. We'd run a strand of baler twine from the single hook to one of the three hooks, then back to the single hook. Then back to the same of the three, then back to the single. We'd repeat until we had three strands of twine running from the single hook to each of the triple hooks. So, three runs of three strands, for nine strands total.
Then we'd crank the back of the triple hooks to put a twist into each of the three runs. Once they were sufficiently twisted, we'd crank the single hook end while someone with a paddle that had three u-shaped slots cut into it would pack the three strands down toward the single hook.
Eventually you got a rope of unknown strength, but it looked great and was a lot of fun.
We used it mostly to tie down gear and make bushcraft items like tee pees, towers, flagpoles, Klondike Derby sleds, etc...
Just a couple years ago I found a piece of it in my old Boy Scout stuff. I picked it up and gave it a tug. It snapped! But it was still a fond memory.
