This looks similar to the crown and wall knot but it is not the same at all. It is traditionally used as a decorative end to a rope. The individual strands do not go through the end of the knot as in the crown and wall
Start with a tight knot. In the case of a length of rope tie a constrictor knot at this point
Tie a counter-clockwise wall knot. Each strand goes under the strand to its left.
Tie a crown knot. Each strand goes over the strand to its left
Take any strand, in this case A and note that it falls directly next to bight b of the wall knot. Bring end A next to b going under 2 crossing points
Do the same with the other three strands
Bring a hemostat (or lacing needle) up under a crossing point and grab the appropriate strand. Pull the strand under the crossing point.
Do the same with the remaining strands, All that remains is to tighten the knot and trim the ends
