double turle knot

Tied in monofilament nylon, the Turle Knot may slip unless another Simple Overhand Knot is made at the end of the line where it leaves the Turle Knot.
It is improved substantially by using the Double Turle Knot.

1. Pass the line through the eye of the hook or swivel.
   
2. Make two simple loops, and carry the line on to make a Simple Overhand Knot around both loops.
   
3. Pass both of these loops over the hook or swivel.
   
4. Pull on both parts of the line to draw the knot up into shape against the eye of the hook or swivel.
