I am stepping into this same situation.
Look a H.C.C.com Honourable Cordwainers Company. There is a lot of info there. A lot of which is free.
There is also 1 book I have found by Tim Skyrme called "Bespoke Shoemaking". I haven't ordered it yet. It seems to contain everything we might need to know.
This is a very all niche in leather work. Not much is available. But see what you can find.
You can get the horse butt strips from Maverick. They are 6 bucks a foot. But each piece is a maximum of 3.5 feet.akes them easy to aquire. I really like them.
Great job on that wallet.
Oh, the ones on his site don't show that little cutaway on the tips of the blade.
I have the French model, the curved detail, and the bevel point knife. That thing is much longer in person.
These will be pryed from my cold dead hands.
The only advices I've seen for skiving is practice, practice, practice.
Wait a minute, I remember someone saying something about using a bottle turned on it's side to aid in skiving. Try that.
Great effort. Your miters look really good. And the cuts for your pockets look great.
I think you would be happier with a 3.85 or 4mm spacing with the stitches. That thread looks a little crowded with 3mm spacing.
Tap your stitches flat. It will make them present a little better.
I also like the color you achieved on the leather. Contrasting thread color is always cool, but it will break a project if it isn't totally clean looking.
Keep working at it, and keep having fun.
