I just learned how to make a monkeys fist two days ago. I've Ben wanting to learn but I was always busy with other things. I made a small one without a core for my keys and I made one using a small marble.
I do a lot of different monkey fist. Here is my 3/4" steel ball bearing key chain. Coming off the fist I weaved the 2 ends next to each other with fuss. Then did a diamond Kong into a trilobite weave with key ring.
