Cut two parts from the strap band. They should easily go around your upper thigh and then have additional 10cm length. Sew one buckle to each of the straps, keep its other end empty. Test the straps in the disc on your leg and adjust their placement so that the buckle will be at a spot that it tightens around your leg. Mark the places where the two straps overlap. Punch a hole into the centre of the markings. This will be the place where the centre screw of the disc will go through.

The strap band will stay in shape if you melt together the fibres of freshly cut ends (and holes), e.g., with a lighter.
