The slip knot is used as a starting point for crochet and knitting.

To untie, all that is required is a smart pull on the end of the rope, which withdraws the loop and causes the knot to spill instantly.

It is used wherever the necessity to cast off suddenly may arise.The slip knot is formed by first creating a loop in the shape of a "p".

Place a hand or hook through the loophole and grab a bight on the working end.

Seat the knot and pull the bight until a small loop is created.
