The Bowline on a Bight is good parallel loop knot to use when you need hand loops to tug on the rope to get it unstuck from a vine-choked branch. It is easy to tie and does not readily jam, so it is usually easy to untie after applying a load.

Step #1
Start with a bight of rope.

Step #2
Form a loop by bringing the end over the standing part.

Step #3
Insert the end of the bight through the loop.

Step #4
Grasp the end of the bight and bring it toward you and down across the bottom of the loop.

Step #5
With your hand still on the end of the bight, drag it beneath all the material that makes up the loop so that it ends up behind the standing part.
