The stitching is standard two needle stitch with beeswaxed
thread. I do it that way so if a single stitch were to wear out or get cut, the remaining stitches will still stay locked for quite awhile. More than long enough to re-do the thing.
The sandwiching is from the flat back being two pieces of leather on either side of the clip mount. This keeps the clip & rivets from scratching the PV.
So each stitch for both needles is going
through 3 layers of leather.
I don't make wimpy stuff. I'm from the school that you spend the time and money the first time so you never have to do that or spend that again.
This is also what kills me when doing house remodleing... Stinking ba
throom took me 10 months, but it's a thing of functional beauty that will be good till long after I'm dead.
