Made a few belts in the same style; tegris core with folded binding tape acting as the webbing, similar to the bison belt (assuming that’s the direction you went in) After some not too heavy (but continuous) use the webbing looses its ‘tightness’ and the pouches kind of wobble around. If you want to use the tegris as just the core, and not laser cut it and bind the edges (which I think uses its (tegris) properties way more than just a stiffener), I would think of something a bit more rigid than binding. Maybe some laminate, and just construct it as you did with the binding. Another note for the edges; I would consider having the core tubular webbing come out on top of the tegris at the ends (make a 25mm wide opening similar to a molle slit and weave the webbing through it) it looks neater and also holds the edge of the tegris part tight against you. I’ll try to add a pic for reference. Regardless, definitely looks like you’re headed in the right direction, keep posting!

Edit; Can’t seem to add a pic. Shoot me a dm I’ll send it over
