Step 1: The Setup:
x. 2 12.5 inch (35cm) pieces of thin (2 mm) cord
Step 2: Begin:
Next take a strand and run it through the opposite 'D' ring (I went 'over' the ring as you can see). Now do the same with the other.
Step 3: The First Knot:
Take the length on the right and bring it over the two main strands.
Now take the left strand and pass in over the strand that was just brought over and then pass it under the two main strands and through the loop that was made by the first strand.
