This is what happens when I get bored and I find scraps of paracord lying about... my childhood summer camp skills come out to play!
I also made a survival bracelet like those sold online. The one I made turned out a little bit too big (I mis-measured the buckle length) so when I went to remake it, my wife, with her years of hemp knotting experience, snatched it up out of my hands and knotted it up in 5 minutes flat (something that took me about 45 minutes the first time around!).
Not too bad for a rank amateur!
