Saddle belt (trick knitting).
At Inokura Leather, one-piece belts are standard, and are carefully finished with a single piece of 5mm-thick harness leather that contains a lot of tannin and is strong.
This time, it was a present for my wife, and she requested that the belt be accented with braid ^^;
The leather was thick and it took a lot of work, but I was able to make something interesting. …Maybe it will become a standard?
