It was a real learning expierience working with unprocessed cord.
First time I didn't tie the knot at the top of the finger loop tight enough, it tore, and I had to splice in some more fibers (which I actually took out of the trash because they were the 'useless scraps') and then retie the knot. Works fine now though.
I had to use every last inch of fiber to get that 25". If you plan on making a sling out of unproccesd cord, make sure you have plenty if material. Its a scary feeling when you have a couple inches left and you only have whisps of fibers.
Cool story with that paracord sling. I agree.
