This knot is the first in the multiple overhand series. It starts with a Simple Overhand Knot, and then the running end is passed through the crossing turn a second time, making the belly-and-spine appearance you see in step 1.

1 Lay down the rope with the running end facing left. Move it down and twist to make the belly, bringing it up over the right side of the standing part.

2 Run the running end up and under the standing part, making two overhand loops.

3 Tighten the knot by pulling on both the standing part and the running end.

Twisting the ends in opposite directions will either help the belly wrap around the spine or impede it, depending on which way they are twisted. The Double Overhand, like all knots in the series, is very secure and difficult to untie.
