The Butterfly Coil
The butterfly coil is the simplest and quickest way to coil and securely store a length of rope longer than 20 feet. It uncoils easily without forming kinks.
Step 1: Double your rope, then hold it at its midpoint. With your hand open and perpendicular to the ground, drape a 3-foot length over the top, forming 11/2-foot coils that hang to either side. Repeat until 6 feet of rope remains.
Step 2: Starting from the bottom, wrap the coils tightly, making sure to wrap over your first turn so that the wraps won’t unwind. Stop a few inches from the top, double the rope you’re wrapping with, and pass this loop through the opening left by your hand. Bring the tag ends over the top of the coil and through that loop.
Step 3: Pull tight. For more security, you can tie an overhand knot around the final loop to keep it from sliding.
