Introduction: Locked Footrope/diamond Knot
The footrope/diamond knot is attractive but can loosen when handled, especially with synthetic slippery cordage. By using the over two crown knot this problem is eliminated.
Step 1:
After tying the last regular crown knot bring any cord over two adjacent cords (instead of one).
Step 2:
Do the same with the second cord
Step 3:
Do the same with the third cord going through the bight of the first cord
Step 4:
Do likewise with the next cord going through two bights. Tighten, If you wish you can stop now and the last crown knot will remain locked in place.
Step 5:
Repeat steps 1 - 4 without tightening completely. Bring any cord under the adjacent cord and up through the center passing under 2 cords (crossing point)
Step 6:
Do the same with the second cord
Step 7:
Likewise with the third cord
Step 8:
and finally with the fourth.
Step 9:
Grab the four ends together in one hand and slightly tighten the knot by grabbing the body of the knot in the other hand and pulling apart. Tighten.
Step 10:
Cut the ends. This technique works equally well with the cobra stitch/solomon bar.
