Knots/Stopper knots/Stevedore knot
Use: The Stevedore knot is a stopper knot, often tied near the end of a rope. It is more bulky and less prone to jamming than the closely related figure-eight knot. This knot is excellent for anchoring a tarp. Pass the end of the rope through a tarp's grommet, tie a stevedore, and anchor the other end with a taut-line hitch. Its added bulk prevents it from pulling through the grommet.
How to tie:
The knot is formed by following the steps to make a figure-eight knot, but the working end makes an additional round turn around the standing part before the end passes back through the initial loop.
