This is a simple easy way to store rope that has several advantages.
It shortens up the length of rope for storage or while in use
It is a great way to store rope because it resists tangles and knots
It is a cheap an easy way to entertain little kids by letting them unravel it
Step 1: Start With a Basic Slip Knot
pass the working end up through the loop and pull to tighten
Step 2: Making the Chain Sinnet
pull to tighten creating a new loop
wash .. rinse .. repeat
Step 3: Finishing the Chain
take the working end of your rope and pass it all the way through the loop
pull to tighten
Step 4: Reducing Your Rope
I started with a 50 foot length of rope and after doing one pass of the chain sinnet weave my rope was about 10 feet long.
weaving it a second time reduced it from 10 feet down to just over 2 feet.
weaving it a third time made it a bundle about 6 inches long (that looked like a tangled mess but still came apart easily).
In order to unravel the rope all you need to do is pull the working end of the rope back through the last loop.
pull working end of the rope until you have unraveled as much of the chain as you need.
