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 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.
Add a Teacher Note to share how you incorporated it into your lesson.
Look at the white bight in the left hand photo. The cord passes UNDER TWO crown knots going from right to left and then UNDER THREE going through the crown. Those extra crossings make a difference compared to
The regular diamond - each strand goes UNDER ONE crown knot and UNDER TWO going back through the crown.
The diamond knot consists of
Crown knot on left. each strand passes over the adjacent strand
Wall knot on right. Each strand passes under the adjacent strand
Step 4: Tying the Regular Diamond Knot
Tie a crown knot and underneath ir tie a wall kmnot
First bring any strand (in this case gray) uthrough the crown
Bring the remaining strands through the crown and tighten
Step 7: Tying the Over Two Crown Knot
First make a crown knot.
Take any strand (in this case grey) and pull it partially through the adjacent bight
Take the next strand (white) and pull it partially through the next bight
Do the same with the next grey strand.
and the last (white) strand
Pull the ends, not too tight so that it looks like the photo. The over two crowns are complete.
Tie a wall knot
Take any strand (grey) and go under two strands (crossing point)in the center of the crown and pulll
Do the same with the next strand (white)
Next the grey strand.
and finally the white. The knot is complete. Tighten.
If you combine the over two diamond with the under two wall diamond you will get a super secure knot
