There are two ways to finish off. Either, unbraid the empty tail of sheath back to
the throat and pull individual strands (or small groups of strands) down under the
main part of the sheath below the throat, just like the three core strands. Spread
these strands around the rope and cut them to random lengths, milking the sheath
to hide their ends. This is a very tedious and often extremely difficult operation
(because of the quantity of material crowding in below the throat), but gives a
neat, tidy and very secure result. Or, if you can’t manage that process, cut the
length of the sheath down and cover it with a tight whipping like that on page
82.
