This bracelet is made with 550 paracord. I gutted the working cords so that it would give it a flatter, more feminine look and feel. But, it works just the same without gutting the cord. The middle core is not gutted. I have found that doing it this way gives the braid a more rounded look.
The formula for the needed cord is (wrist size in inches) / (.17). It will give you measurement in inches. Sorry metricites. For example, if you are making one for a 6.5 wrist, then you'll take 6.5 / .17 = 38.23. So, you'll need a little over 38 inches of cord for "both" cords. If you are using 4 colors, then you'll need 19 inches of both color. Fused together, this will give you 38 inches. Yeah, I know. I'm a genius. Since I used 550 cord, this formula might be a little off if you are using 450, micro cord, or even 650 and above.
Tying this works best on a paracord jig of some sort, but it is not necessary. The jig allows you to keep the core tight as you braid the cord.
I have tried to include enough pics in order for you to see every step, but feel free to comment and ask questions if there is any confusion.
Step #1: fuse cords together. Don't worry about how ugly the connection looks. You are going to hide it in the hitch.
Step #2: Tie a hitch knot on the buckle. If you don't use buckles, you can just tie the hitch using the loop method
Step #3A: loosen hitch knot and run cords through so that the fused part is in between it. This will hide any ugliness.
Step #3B: just another angle of the cords going through the hitch
Step #4: re-tighten the hitch so that it cinches down on the fused cords.
Step #5: You can start with either side. I started with the top left cord. Take that cord under the core, in between the other two cords, and down over like the pic shows.
