Where the leather starts, and what happens to it before it leaves the bench.
A walk through the three stages that determine what an Officium piece becomes in your hand: the hide we pick, the way it is tanned, and the workshop process that turns the hide into a sleeve.
The hide is picked before the design is picked.
We do not start with a sketch. We start with a hide. Every Officium piece is matched to a specific lot from Horween — a family-owned tannery on the northwest side of Chicago that has been finishing leather since 1905 — before any cutting pattern is drawn.
The hides we use are full-grain Horween — the strongest, densest layer of the hide, with the original grain pattern intact. Horween does not offer a commodity line; every grade they sell is a deliberate choice by the tanner, not a byproduct of splitting off the more expensive top layer. We work with what the animal actually produced, defects and all.
Each lot is logged with the supplier name, grade, weight (in ounces), and the section of the hide it came from. A 4 oz shoulder is not interchangeable with a 4 oz butt — and the sleeve you are buying is matched to the part of the hide its shape actually needs.
Vegetable-tanned. Slow. The way leather was finished before chemistry got cheap.
Every Officium hide is vegetable-tanned at Horween — that is, tanned using tannins extracted from bark, wood, and plant matter, in the same brick pits on Chicago's northwest side that the company has run since 1905. The process takes thirty to sixty days. There are no chrome salts, no synthetic shortcuts.
Vegetable tanning produces a hide that leaves the Horween plant firm and pale. What darkens into the deep amber patina you see on a six-month-old Officium sleeve is not a finish applied at the tannery — it is the hide absorbing light, oil, and use on the owner's desk. The color is earned, not applied.
The tannins come from renewable plant sources that re-grow on a human time-horizon. Horween publishes its process openly — the pit times, the tannin sources, the effluent treatment — because it has nothing to hide. Chrome tanning, the industry default, produces a softer hide faster but leaves chromium salts in the waste stream for decades. We do not work with chrome-tanned leather. Neither does Horween.
Three steps. One piece on the bench at a time.
What happens to the hide between the tannery and your hand: a single workflow, run one piece at a time, on a wooden bench in Atlanta.
Cut and re-stitch the pattern.
The pattern pieces are laid out by hand on the back of the hide, not on a CAD table. The maker chooses which cut fits where based on the actual grain of the hide in front of them, not a pre-optimized marker. Each panel is cut once, with a single knife pass — no skiving, no sanding.
Saddle-stitch the seams.
Every seam is hand-stitched with two needles working from opposite sides of the same stitch hole. The thread is waxed linen, laid down one stitch at a time. There is no machine on the bench — a saddle-stitched seam locks itself, so a single broken stitch cannot unravel the row. This is what gives an Officium piece its structural longevity.
Burnish, stamp, and finish.
The exposed edges are slicked down with beeswax on a wooden burnisher, until they catch light like glass. The maker’s initials are stamped into the interior lining. The hardware is fitted, the thread is waxed a final time, the piece is inspected, and only then does it ship.
Every hide is logged before it goes on the bench.
Each piece of leather used in an Officium sleeve is logged by supplier, grade, and weight in the workshop ledger. The ledger is the same one the maker uses to estimate batch yields and reorder lead times — it is not marketing material, it is operations.
