1. Make loop approx. ½", wrap the short end "B" around the mainline "A". Put the left hand thumb over the wrapping so the loop will be fixed (marked with a ring at the scetch).
2. Take the other part of the lead and make a loop linked into the first loop. Pull both lineends through the linked loops, one from each side.
3. Pull short ends "B" and "D" first, then the long ends "A" and "C". Moisture with saliva when thighten knot. Trim short ends.
