Knowing how to quickly tie knots is important when fishing so you can spend less time messing with your line and more time ripping lip. Here’s a video that will show you how to easily tie the perfection loop knot for the next time you’re on the water.

In case you missed anything, here’s a step by step breakdown:
1.) Holding the line in your left hand, use your right hand to make a loop in the line and transfer the line to your left hand
2.) Take the tag end in your right hand and feed it behind the pinched loop of your left hand and pinch it so you know have two loops
3.) Grabbing the tag end again feed it between the two loops, then go through the first loop and grab the second loop and pull everything tight

Keep in mind this knot is great for when you need to have a loop at the end of a line.
