Ok, so basically 2" webbing passed through a metal slider, and then sewn back onto itself. That's a good way to do it. It allows you to have a good amount of stitch-able area for your bar tacks/box stitch/zig zags. I still HIGHLY recommend T90 thread or bigger. If you're having any reservations at all, please PM me. You can't afford for these two sets of stitches to be inferior in strength in any way. I'd be happy to help you out with this.
