Step 1: Collect Your Materials
For this particular project, I've grabbed two cords at about three feet each. Make sure you have something sharp to cut with, your fire making device to finish the project, and any additional swag (key rings or carabiners) that you wish to attach at the end of the project.
Step 2: Prepare to Tie
Once you've either gutted or not gutted, find the center of each cord. This is easily done by draping it over your finger and touching the ends together. Stretch it tight and you have found the center.
Now you're going to run the cords perpendicularly to each other - right angles, 4-way intersection - however you wish to describe it. Once you have this accomplished, squeeze the cords between your finger and thumb and flip it over.
Step 3: Start Tying
As I've tried to show in the pictures above: I started with the 6 o'clock strand and ran it to 11 o'clock and laid it over. This differs from the Box Knot in that we are off-setting the knot to get the round shape. Next, I moved to the 9 o'clock strand and ran it to 2 o'clock and laid it over. Next, the 12 o'clock strand is run to 5 o'clock and laid over. Finally, the 3 o'clock strand is brought across and tucked through what was originally the 6 o'clock strand.
Step 4: Tighten It Up!
Once you're satisfied with the tightness, continue on with the knotting from the previous step. It really doesn't matter which strand you start from as long as you always go the same direction and remember to do the over, over, over, through as we did in the previous step. You should also be able to see from the above pictures that we are not going directly over the previous strands. We are off-setting as before so that we get the round shape to this knot.
Once you've done a few knots, you can safely pull the whole thing off your blood-deprived finger and take a break, tighten the top, or just admire your work. You can already see the beginnings of the spiral at this point.
