Tying Knots

The problem with knots comes as a surprise to everyone who's new to fishing.
If you tie a lure to the end of the line with a simple knot, and then pull, the line slips and the knot comes undone.
The secret is to wrap the line around several times before completing the knot. This type is called a clinch knot. There’s debate as to how many times to wrap the line – four, five or six times. Five will work fine for now. To see, do a “clinch knot” video search.
One thing you’ll want is a nail clipper to trim off the extra line after the knot is tied. You want your knot and line to be as close to invisible as possible.
[There is also the improved clinch knot, and it is an improvement. But don’t worry about it now.]
