i decided to try and make a 2 point paracord sling. got it weaved and got the tails on the end of the extra cord. what do I do to finish it so it doesn't come unwound??
Nylon para cord? Heat. Melt the ends like you would polypropylene rope. Soldering iron will likely give you more control than a propane torch.
Way down at the bottom, the guy says, "Melt the ends." http://www.instructables.com/id/Paracord-Rifle-Sling/?ALLSTEPS
