Forty years ago my father the Scoutmaster taught me to cut paracord into 15-20' lengths, and melt the ends.

A 100' length of cord makes six 16.6' cords. The size is perfect for using with tents, storm tie-downs, backpacks, lashings, ... and lengths can be combined if needed.

Storage was simply wrapping each length around the four fingers until the "tail" left is a bit more than 1 foot, and then bundling it in the middle with a few loops that are locked down by two locking loops (like a clove hitch).

Its fast and simple.
