What It Does: Creates a loop in a line while maintaining most of the line's strength.
Why It's Useful: Used to attach a second leader, lure, or fly to a line.
How to Tie It:
1. Make a circular loop in the line.
2. Wrap one end through the loop.
3. Where each end meets the loop, make3 to 5 twists as shown then - without letting the twists unravel - pull the loopthrough the hole between the two sets of twists.
4.While holding the dropper loop in place (do not pull on the loop - just be sure it doesn't come out) pull on both ends of the line to bring the wraps together.
5. You now have a loop to which you may attach a bait, fly, or leader using another kind of knot.
