Buyers rarely lose money on a bespoke bag programme because of a technical failure. They lose it because two parties used the same word to mean different things. Bespoke itself is the clearest example: to some it means a pattern cut from scratch, to others a stock bag with a logo. This glossary sets out the working vocabulary of a bespoke bag programme — design, materials, construction, hardware, production, quality and compliance — in the sense each term is used on a production floor, so that a brief means one thing to everyone reading it, and a specification can be verified rather than argued about.
Why Terminology Matters in a Commission
A specification is a contract expressed in nouns. If the noun is ambiguous, the obligation behind it is ambiguous, and the failure will be discovered at inspection rather than at briefing. That is the practical reason to fix vocabulary early: it converts every later conversation from interpretation into verification. A buyer who can name the edge finish, the skive and the tolerance will get a different quotation, a different sample and a different outcome from one who asks for a nice leather bag.
Terminology also travels badly across borders and between disciplines. A designer, a pattern cutter and a compliance officer use overlapping vocabularies with different precision, and the buyer sits between them. The definitions below follow production-floor usage, which is the version that determines what is actually made. Where a retail or marketing usage differs materially, that difference is noted, because those are precisely the terms that cause disputes.
- Ambiguous nouns produce ambiguous obligations, which surface at inspection rather than at briefing.
- Production-floor usage determines what is made, so it is the version worth learning.
- Retail and marketing usage often differs from technical usage on the same word.
- A shared glossary shortens quotation, sampling and approval cycles measurably.
- Naming a term correctly signals competence, which changes how a brief is received.
- Terminology is the cheapest quality control available — it costs nothing to get right.

| Equipment | 149 machines including computerised saddle-stitch and edge-painting units |
| Monthly capacity | 200,000 pieces |
| Entity | Founded 2014; principal has worked in bag development since 2004 |
These are the terms that appear in the first conversations of a programme, and they describe the documents and artefacts that carry the design from idea to approved sample. Confusion here is expensive because it affects everything downstream: a tech pack that is really only a sketch will be quoted as a sketch, and the difference appears later as a dispute about what was included.
| Term | What it means in practice |
|---|---|
| Bespoke | Developed from the buyer brief, with a pattern cut for the programme |
| Made-to-measure | An existing pattern adjusted in size, proportion or detail |
| Customised | A stock product altered by colour, material or branding choice |
| Private label | Production carrying the buyer brand name; says nothing about development |
| Tech pack | The specification document: dimensions, materials, hardware, construction, packing |
| Pattern | The card or digital template from which panels are cut |
| Toile | A test version in cheap material, used to check shape before cutting leather |
| Prototype | The first physical build of a design, usually before refinement |
| Counter sample | A sample made to match a reference supplied by the buyer |
| Pre-production sample | A sample made on the production line, using production materials and tooling |
| Revision | A numbered iteration of the design or specification |
| Silhouette | The outline or overall shape of the bag |

Leather and Material Terms
Material vocabulary is where marketing language does the most damage, because several of the most reassuring-sounding terms are the weakest technically. Genuine leather sounds like a grade and is not; it simply means the material contains leather fibre. The terms below are the ones that actually constrain what a tannery supplies and what a maker can cut from it.
| Term | What it means in practice |
|---|---|
| Full-grain | The top layer of the hide, uncorrected, with the natural grain intact |
| Top-grain | The top layer after light correction or sanding of surface imperfections |
| Corrected grain | Surface sanded and an artificial grain embossed to hide defects |
| Genuine leather | A weak trade term meaning it contains leather; not a grade |
| Bonded leather | Leather fibre bonded with adhesive; not suitable for quality bags |
| Substance | Leather thickness, usually stated in millimetres |
| Tannage | The tanning process: chrome, vegetable, or a combination |
| Aniline | A transparent dye finish with no pigment layer; marks and patinas readily |
| Semi-aniline | Light pigment plus dye; some protection, some natural character |
| Pigmented | An opaque surface coating giving uniform colour and stain resistance |
| Saffiano | A cross-hatch embossed, coated finish that resists scratching |
| Patina | The surface change leather develops through use, light and handling |
Two further terms appear constantly in material specifications and are worth stating precisely, because they are used loosely even by experienced buyers. Temper describes how firm or soft a leather feels in the hand, and it is a finish decision as much as a tannage one: the same hide can be milled soft or left firm. Cut refers to which layer of the hide is used and where on the hide it came from, which is why panels from the shoulder behave differently from panels taken near the belly.
Construction and Craft Terms
Construction vocabulary describes operations rather than materials, and it is the vocabulary that separates a buyer who can specify a bag from one who can only describe it. These terms are the ones worth using deliberately in a tech pack, because each corresponds to a decision that affects how long the piece lasts and how much it costs to make.
| Term | What it means in practice |
|---|---|
| Skiving | Thinning leather at an edge or fold to reduce bulk |
| Edge paint | A liquid coating applied in thin coats to finish a raw edge |
| Burnishing | Finishing an edge with heat, wax and friction instead of paint |
| Turned edge | The leather folded over and stitched, hiding the raw edge |
| Binding | A strip of material stitched over a raw edge to cover and protect it |
| Piping | A cord or folded strip inserted in a seam as a decorative or structural line |
| Gusset | The panel giving a bag depth and determining its capacity |
| Interlining | Reinforcement material between shell and lining that gives structure |
| Stitch density | Stitches per inch; higher generally means stronger and finer-looking |
| Saddle stitch | A two-needle hand stitch that does not unravel if one stitch breaks |
| Load-bearing seam | Any seam carrying the weight of the contents; should be stitched, not glued |
| Clicker press | A press using a shaped blade to cut panels consistently |

Hardware and Component Terms
Hardware is the component category buyers specify least precisely and reject most often, largely because plating tone and alloy are difficult to describe in words. The practical solution is to specify by standard and to approve a physical sample, but the vocabulary below allows the specification to be written accurately in the first place, which reduces the number of samples needed.
| Term | What it means in practice |
|---|---|
| Plating | The metal coating applied to hardware; tone and durability vary by standard |
| Finish | The surface appearance: polished, brushed, antique, matte |
| Zamak | A zinc alloy common in bag hardware; economical and easily plated |
| Solid brass | A heavier, more expensive alloy that patinates rather than pitting |
| Nickel-free | Plating without nickel, required by some markets and buyers |
| Slider | The moving part of a zip that opens and closes the chain |
| Puller | The tab attached to a slider, often branded |
| Turn-lock | A rotating closure commonly used on flaps |
| Foot or stud | A small fitting on the base that keeps the bag off the ground |
| Rivet | A permanent metal fastener used with or instead of stitching |
| D-ring | A ring fitting used to attach straps |
| Swatch card | Physical material and hardware samples approved for the programme |
Production, Quantity and Commercial Terms
These terms govern the commercial shape of a programme: how many, how long, who pays and who carries risk. Misunderstanding here tends to produce not a defect but a cash-flow or schedule problem, which is often more disruptive than a quality issue. Standard programme parameters are a minimum order quantity of five hundred pieces per style and colourway, sampling in six to ten working days and bulk in thirty-five to fifty days after sample approval.
| Term | What it means in practice |
|---|---|
| MOQ | Minimum order quantity; five hundred pieces per style and colourway as standard |
| Colourway | One colour version of a style, counted separately against the MOQ |
| Small-batch pilot | A reduced quantity run used to validate demand before committing |
| Lead time | The total elapsed time from approval to delivery |
| Sampling | Development of the sample, six to ten working days for standard constructions |
| Tooling | Custom dies or moulds made for a programme; a fixed cost |
| FOB | Free on board; risk transfers when goods are loaded at the named port |
| EXW | Ex works; the buyer collects and carries risk from that point |
| CIF | Cost, insurance and freight to the destination port |
| DDP | Delivered duty paid to the buyer destination |
| T/T | Telegraphic transfer; standard terms are thirty per cent deposit, seventy before shipment |
| Price break | A quantity threshold at which the unit price reduces |

Quality, Inspection and Compliance Terms
Quality vocabulary is the language of the last stage of a programme and it should be agreed at the first. The terms below define what passes, what fails and what is legally required in the destination market. Agreeing them early is what makes an inspection a measurement rather than an argument, and it is the point at which a specification stops being a description and becomes a standard.
| Term | What it means in practice |
|---|---|
| AQL | Acceptable quality limit: the defect threshold at which a shipment passes or fails |
| AQL 2.5 | The common standard for leather goods under ISO 2859-1, general level II |
| Single sampling | One sample drawn and inspected per lot under the stated plan |
| Major defect | A fault affecting saleability or function |
| Minor defect | A cosmetic fault within tolerance but below the major threshold |
| Critical defect | A fault making the product unsafe or non-compliant |
| Tolerance | Permitted deviation from a stated dimension |
| REACH | The European Union regulation on restricted chemical substances |
| CPSIA | United States consumer product safety requirements, including children's goods |
| OEKO-TEX | A certification system for textiles and leather tested for harmful substances |
| LWG | The Leather Working Group protocol auditing tannery environmental performance |
| ISO 9001 / 14001 | Quality management and environmental management system standards |
Terms Buyers Commonly Confuse
The pairs below account for a disproportionate share of briefing disputes. Each pair contains two terms that are used interchangeably in conversation and mean materially different things in production. Learning to distinguish them is the fastest way for a new buyer to improve the quality of a brief, and it is the cheapest way to avoid a sampling round spent correcting a misunderstanding.
| Commonly confused | The distinction that matters |
|---|---|
| Bespoke vs customised | Bespoke is developed; customised is a stock item with choices applied |
| Private label vs bespoke | One governs branding, the other governs development |
| Genuine vs full-grain | Genuine is not a grade; full-grain is the top uncorrected layer |
| Prototype vs pre-production sample | One tests the design; the other is made on the production line |
| Edge paint vs burnishing | One applies a coating; the other finishes with heat, wax and friction |
| MOQ vs price break | The minimum you may order, and the quantity at which price improves |
| AQL vs defect-free | AQL permits a defined number of minor defects; zero-defect is a separate requirement |
| FOB vs CIF vs DDP | Where cost and risk transfer, respectively at loading, at destination port, at door |
If you cannot name it, you cannot specify it. And if you cannot specify it, you cannot complain about it later.

Frequently Asked Questions
What does bespoke actually mean when commissioning a bag?
It means the piece is developed from your brief, with a pattern cut for the programme, materials selected by you and a sample submitted for written approval before bulk production. It does not mean a stock bag with a logo added. That is customisation or private label work, which is legitimate but involves no development and should be priced differently.
What is the difference between a tech pack and a sketch?
A sketch communicates what the bag looks like; a tech pack states what it is made of and how it is assembled. A complete tech pack includes dimensions with tolerances, material specification with substance and finish, hardware specification with plating standard, lining, stitch density, edge finish, branding placement and packing method. Most programmes need both documents.
Is genuine leather a quality grade?
No. Genuine leather is a trade term meaning the material contains leather fibre, and it spans a wide quality range including heavily corrected and bonded products. The terms that carry real information are cut — full-grain, top-grain or corrected — together with substance, tannage and finish. Specify those and the material can be verified on arrival.
What is the difference between full-grain and top-grain leather?
Full-grain is the top layer of the hide with its natural grain intact and uncorrected, which is why it develops patina and is the most durable cut. Top-grain has been lightly sanded or corrected to remove surface imperfections, giving a more uniform appearance at slightly lower durability. Both are legitimate choices depending on the look required.
What does MOQ mean and why is it per colourway?
MOQ is the minimum order quantity, standard at five hundred pieces. It is counted per style and per colourway because each colourway requires its own material purchase, dye lot and line setup. Three colourways of one style therefore means three minimums unless the programme agreement explicitly pools them, which is worth negotiating at brief stage.
What is a pre-production sample?
A sample made on the production line using production materials, tooling and operators, rather than in the sampling room. It is the last checkpoint before bulk and is the most reliable predictor of what the shipment will look like. For complex programmes, approving a pre-production sample is worth the additional time it adds to the schedule.
What does AQL 2.5 mean in plain terms?
AQL is the acceptable quality limit: the number of minor and major defects a shipment may contain before it fails inspection. AQL 2.5 under ISO 2859-1, single sampling, general level II is the common standard for leather goods. It permits a defined number of minor defects, so a buyer wanting zero defects must state that separately and expect it to affect cost.
What is the difference between edge paint and burnishing?
Edge paint is a liquid coating applied in several thin coats, sanded between, producing a smooth sealed edge. Burnishing finishes a raw edge with heat, wax and friction, giving a slightly darker, more natural edge typical of vegetable-tanned work. Painted edges can be refinished; burnished edges are maintained rather than replaced.
What is skiving and why does it matter?
Skiving is thinning leather at an edge or fold so that overlapping layers do not create bulk. It matters because unskived seams produce thick, uncomfortable joins and visible ridges under the surface. Proper skiving is one of the clearest indicators of skilled construction and is largely invisible in a photograph, which is why it should be checked on a physical sample.
What does substance mean when specifying leather?
Substance is thickness, usually stated in millimetres. It should be matched to the silhouette: lighter substances around 1.2 to 1.4 millimetres for soft, slouchy shapes, and heavier around 1.8 to 2.2 millimetres for structured pieces. Specifying substance prevents the common problem of a bag that looks right in photographs but collapses or stands incorrectly in person.
What is the difference between FOB, CIF and DDP?
They are Incoterms defining where cost and risk transfer. FOB means risk passes when goods are loaded at the named port, and is the standard quoting basis for bag programmes. CIF adds carriage and insurance to the destination port. DDP delivers duty paid to the buyer door. The choice determines who bears loss in transit and who handles customs.
What is a swatch card and why is it important?
A swatch card is the set of physical material and hardware samples approved for a programme. It is the reference against which production is checked, and it is what makes a reorder possible years later when dye lots have moved. Approving colour from a screen rather than a physical swatch is one of the most frequent causes of rejection on arrival.
What does nickel-free hardware mean?
It means the plating contains no nickel, which matters because nickel is a common contact allergen and is restricted in some markets. Where a programme sells into a market with nickel restrictions, or where recipients have known sensitivities, specify nickel-free plating in the tech pack and confirm it on a physical hardware sample before bulk production begins.
What is a load-bearing seam?
Any seam that carries the weight of the contents, such as handle attachment, strap joins and base seams. These should be stitched rather than adhesive-bonded, and usually reinforced as well. Specifying how load-bearing seams are constructed is one of the most effective things a buyer can do to determine how long a bag lasts.
What is a small-batch pilot?
A reduced quantity production run used to validate demand, presentation and quality before committing to a full minimum order quantity. It uses the same development process as a full programme, so the pattern and specification remain available for scale-up. The trade-off is unit cost, since fixed costs such as tooling and sampling are spread across fewer pieces.
What is the difference between a prototype and a counter sample?
A prototype is the first physical build of an original design, made to test whether the idea works in three dimensions. A counter sample is made to match a reference supplied by the buyer, usually to test whether a maker can reproduce an existing specification. Both precede the pre-production sample, which is made on the production line itself.
