Step 1: Bringing together what you need.
Step 2: Threading the buckle end.
Fold the paracord in half and thread it thru the face side of the buckle. Pull it so the end of the cord are even. Once even pull cord tight against itsself.
Step 3: Melting the cord ends.
Note: all that has to be done is heat the ends enough to melt it, not catch the cord on fire.
