Moderate · 6-step tie
Double Uni Knot
Connecting main line to leader
Overlap both lines
Overlap about 6–7 inches of the main line and leader.
Form the first loop
Using the main-line end, form a circle that lies over both lines.
Wrap the first side
Pass the main-line end exactly six times around both lines through the circle, then pull that end to snug the first Uni.
Repeat on the leader
Using the leader end, form a matching circle over both lines on the opposite side.
Wrap the second side
Pass the leader end exactly six times around both lines through its circle, then snug the second Uni.
Draw knots together
Moisten and pull both standing lines in opposite directions so the two knots slide together and seat.
Why it matters
