I can tell you from my old tool belt I see you learning to saddle stitch.lol A heavier oil tan leather would work nice for the pouches. 7/8 oz. The belt I would do two layers of 5/6 sewed flesh to flesh. Give you a nice sturdy belt that would last years. Plenty of info in dif places on this site. I know I've seen a few tool belts on here. So can probably get some other opinions and maybe a pattern. Good luck.
