over two crown and under two wall diamond knots

The diamond knot is an attractive stopper knot but can loosen when handled, especially when nylon or other synthetic material is used.
Using the over two crown knot or under two wall knot increases the number of cords that each strand passes under.
That increase in crossings makes the knot much more secure than the regular crown knot.
