I made 4 turns around my monkey fist jig and then instead of going as usual I went Under 2 strands, over 2 strands, then over2, under 2 to split the sides into 4 segments. I repeated this action in the third set of turns so that each face of the monkey fist has 4 segments.
I made my jig from a block of wood and 4 dowels similar to this (sorry, no personal photo)

Here is a bent bit of clothes hanger. Size it to the diameter of the core you are covering. MUCH easier than tying around your fingers and less cord required (I have fat fingers). Tony
Use the wooden jig for the split faced knot. Pull out the dowels to release the knot. The bends in the wire jig make it very difficult to release the knot. Tony
