I was just thinking that not everyone finds it easy making the monkey fist knots between 2 fingers so I made this DIY aid I call it the "Easy Monkey Fist". All that is needed is to wrap the cord correctly in the monkey fist knot then take it off and tighten it.
It's made from scrap timber (L-shape screwed together) and 4" nails. I drilled nail sized diameter holes so the nails could be removed / pulled out easily.
The small gap on the base is for holding the start cord.
3 screws (optional) to fix it to a solid bas.
It is optional to drill a few more holes to fit different marble/small ball size.
I tried it myself a few times and it only took me a few minutes to make a perfect monkey's fist.
Just remember, do it slowly dont pull to hard on the first few tightenings.
In this guide I used a large marble so 6 times around was enough to cover it.
Also remember the bigger the core object is the more paracord you will need + extra cord for final finishing: snake knot, cobra knot etc'.
