See detailed instructions below for each step in tying the Loop-Loop Connection.
  1. Pass the loop on the line through the loop on the leader.
  2. Pass the end of the leader through the loop on the end of the fly line.
  3. Pull the line and the leader away from each other, until the loops slide together to form what looks like a square knot. You may have to help the knots pass through the loops with your fingers.
