(Also known as a Thumb Knot)
This knot is so natural that it probably does not need to be taught. It must be named however since it is one of the most fundamental knots that is used to form many others.
This knot is also popular for securing the end of a line to prevent it from pulling back through an eye or another knot.

2. Bring the running end around the standing part of the rope starting to feed the running end through the center of the loop.
3. Feed the running end through the loop.
4. Pull both ends of rope outside the loop to tighten knot.
5. Dress and set the knot.
