I need to know how to tie a fisherman's knot.

A fisherman's knot is used to attach a rope to a pole, or a pole to another pole.  They’re a useful knot to know because they’re very easy to tie and secure.  I’m also happy to teach you a different type of knot you might use for tying that’s more secure, but it will take a while longer to tie, and I won’t be able to teach you to untie it.

Okay so how do I make the fisherman's knot?

A fisherman’s knot is the easiest of all knots to make, so I’m going to assume you don’t know how to tie any other knots.
