under the standing part, then drop the bight over the top of the post. Then make a bight in the rope on the other side of the standing part and drop it over the post. Note that in each placement of a bight over the post, the end's side of the bight should lead to the side away from the standing part--this will make casting off easier. Continue this repetition as necessary until secure (usually three bights). Finish by half-hitching a bight around the standing part or a round turn about the post. With heavy loads, it is important to have made enough bights and turns to reduce force on the final turns or a hitch--otherwise, it will be difficult to untie (a hitch) or may slip.
Knot
A knot is a method of fastening or securing linear material such as rope by tying or interweaving. It may consist of a length of one or several segments of rope, string, webbing, twine, strap, or even chain interwoven such that the line can bind to itself or to some other object—the "load"...

Tying
To tie, take a single turn or a round turn around the post. Pass a bightBight (knot)
In knot tying, a bight is a curved section, slack part, or loop between the two ends of a rope, string, or yarn. The term is also used in a more specific way when describing Turk's head knots, indicating how many repetitions of braiding are made in the circuit of a given knot.-Slipped knot:In order...
