This knot is similar to the regular Bowline, except that you start out by folding the end of the rope into a bight.

1 Make a crossing turn and bring the end up through it.

2 Open up the end loop and bring it down and under the two loops.

3 Bring the end loop up behind the standing parts and tighten down.

The Bowline in the Bight is quick, fun to tie, and makes a nice double loop. If tied near the end of a rope, the running end can be secured to the standing part with yet another Bowline. Just make a crossing turn in the standing part and bring the running end up through it, around the standing part, and back down through the crossing turn just like in a Bowline. This can be done with any knot where the running end comes out of the knot parallel to the standing part.
