The Double Fishermans Knot
How to Tie It & When to Use It

Stage 1

Lay two lines together and take the right-hand (yellow) one over the left-hand (red) one;

Stage 2

Pass working end of the yellow line under its own standing part and the red line's working end working from left to right;

Stage 3

Do the same again forming two loops around the red line;

Stage 4

Now tuck the working end of the yellow line back through the two yellow loops, and tighten the knot (it's a double overhand knot) around the red line;

Stage 5

Transfer your attention to the red line and repeat the process to form two red loops.

Stage 6

Tuck the working end of the red line through the two red loops from left to right.

Stage 7

Cinch the red double overhand knot up tight.

Stage 8

Pull the two standing parts until the two knots are jammed together - and that's it, you've tied a double fishermans knot.
