I'm not ghostrider, but I can generally do a monkey fist in an hour, more or less. It depends on the cord size and fist size desired. I usually start with a figure 8 knot, and tuck it inside for a core on the next wrap, usually two loops per side, then do a third layer with three or four loops per side, and so on until I get the size I want (or run out of cord )
Don't expect to do one fast until you have done a bunch (I learned in the US Navy, 25 years ago. I have a bunch of practice, even if I don't take a lot of pictures )
I don't believe in safe queens, only in pre-need replacements.
