Made with 550 paracord. The main strap (black) has the inner strands removed and then fused together to make a loop. You need to measure the length for your hand. Next I used tan with the inner strands removed and made a Cobra weave for all but a half inch or so on either end. Then I took a full piece of black and tan and fused them together, inner strands were left in, and I did another Cobra weave starting about a half inch before the previous weave and ending and equal distance after. I did this to get a small taper and to get a little more size to it.
To install I looped it through strap mount on the Capture clip plate. I then did the same on the strap mount. You need to ensure you leave enough of a loop to be able to pass the plate through. Then mount the plate.
To make it wider you can do what I did with layering it.
