Y'know, like the ones at the store when the leads are all tied?
First, you take a lead rope.
String the end of the lead rope through the jump ring.
Tighten it to an appropriate length.
Repeat step 2 so that there are 2 ropes in the ring.
Twist the end of the rope around the loop.
Keep twisting and when done, take the loose end and tie it off with the remaining loop.
