Home — Craftsmanship — Stitching Technique
The same seam can be sewn two ways. One survives a broken thread; the other unravels from it. That single engineering difference is why fine leather is still hand-stitched in an age of machines.
The Technique
A saddle stitch is sewn by hand with two needles on the two ends of a single waxed thread — traditionally linen. The maker first marks and pierces the line with a pricking iron or awl, then passes both needles through each hole from opposite sides, so the two ends of the thread cross and lock inside the leather at every single stitch. The holes — and the thread — sit at a forward slant of roughly 45–60°, the classic luxury "slanted" stitch line, which also increases the thread's contact with the leather and spreads stress.
A machine lockstitch uses two separate threads: an upper needle thread pulled down to loop around a lower bobbin thread. It's enormously faster — under a minute where a hand-sewn small wallet takes 45 to 60 — and perfectly fine for many goods. But it fails differently.
Why It's Stronger
"If the thread rips on a lockstitch, then the entire integrity of that stitching line is compromised … with a saddle stitch, if a thread rips, the only area that is compromised is at the rip."— Craig Wesleys leatherworking reference
Because each saddle stitch is independently locked, a cut or worn thread stays put instead of running — the seam can't unravel down the line the way a damaged lockstitch can. It's widely considered one of the strongest stitches in leatherwork, which is why a handful of luxury houses still hand-sew despite the cost.
Higher stitches-per-inch (the 8–10 band) signals fine work; the uniform forward slant is the visible fingerprint of a hand. A perfectly flat, straight stitch line is the mass-production tell.
How Louisiana Makers Do It
New Orleans maker Micah McGrath states the standard outright:
"Every single stitch is done by hand."— Micah McGrath, Micah McGrath Leather Works (micahmcgrath.com)
And Cocodri's Mary Tutwiler ties the stitching to the promise the whole piece makes: "A lot of care goes into each piece, into every detail … My goal is to design beautiful, practical pieces that will last a lifetime." The saddle stitch is how that promise is physically kept.

Open the piece up — the lining tells you as much about quality as the skin on the outside.
