I'm not sure what you're asking but I'll hazard a guess. I made the .5mm hook much smaller by sanding it down with 220 sand paper and then using the hard edge of some stainless steel scissors I polished it smooth. Then I used a pocket knife to shape the inside of the hook. The loops you see here my hook can fit into them. I just need a better pair of magnifying lenses now so it's easier to see.
