Paracord is a great material to work with, except for the fact that the ends fray pretty badly.
I figured out a way to finish the ends with minimal effort and without burning yourself.
Of course we all know how to burn the ends of paracord.
But, this leaves a "bulb" at the end that can make it difficult to weave through whatever you are working on.

My solution: SPIN IT

Materials:
Paracord
Lighter
Knife, scissors, or other cutting implement

Step 1: Burn the Paracord

Burn the paracord like normal.

Let the end get good and melted.
You want the inner core to "combine" with the outer sheath

Step 2: Spin It

Blow the flame out and QUICKLY spin the end.

This cools the end and keeps it from bubbling up.

CAUTION:
You are spinning the molten end of a burning piece of a plastic/nylon string.
There will be little drops of molten string that will fling off.
So do this outside or in the garage.

Step 3: Trim the End

During the spinning process you may get a long "hair" on the end.
Trim the "hair" off with whatever cutting tool you prefer.
You could even gently reheat it to smooth out the end.
