In a leathercraft workshop, inventory management often begins with a clear mental picture of a few fresh hides. However, as those hides are cut into a growing stash of offcuts and remnants—and as thread, hardware, and dyes accumulate—remembering exactly what remains becomes increasingly difficult. Relying on mental estimates or visual checks, often referred to as the “Mk1 Eyeball” method, frequently leads to inaccurate stock counts and interrupted workflows.
What this article covers
This article defines the essential data fields required for professional-grade material tracking and explains why keeping an accurate running count of remaining stock matters in the first place, regardless of whether that count is kept on paper or updated automatically. We will outline the specific parameters for leather and consumables, as well as the logic behind automatic stock deduction for those using a digital system.
Essential Record Fields for Material Inventory
To maintain an accurate digital representation of a physical stash, materials should be categorized and logged using specific, standardized fields.
Material Classification Records should first be sorted by type: Leather, Thread, Hardware, Dye, or Other. This allows for filtered views and category-specific management.
Specific Leather Parameters For leather specifically, the following fields are necessary to ensure the reproducibility of projects:
| Field | What It Captures |
|---|---|
| Tannery | The source (e.g., Horween, Wickett & Craig, or Hermann Oak) — critical for matching grain and quality. |
| Leather Type | The tanning method and style, such as Veg-Tan, Chromexcel (CXL), or Chrome-Tan. Veg-Tan is firm and develops a patina over time; Chrome-Tan offers immediate softness and greater initial water resistance. |
| Thickness | Recorded in ounces (oz), to ensure the structural integrity of the design. |
| Finish | The surface treatment, such as Natural, Dyed, Waxed, or Pull-up. |
| Color | The specific shade provided by the supplier. |
Quantity and Units Accurate tracking requires defining both the quantity and the appropriate unit of measurement:
| Material | Unit |
|---|---|
| Leather | Square feet (sqft) |
| Thread | Meters (m) |
| Hardware | Count (unit) |
| Dye | Milliliters (ml) |
Financial and Sourcing Data Recording the unit price and purchase source allows for precise cost calculation and easier reordering when stock levels run low.
Why Knowing Your Remaining Stock Matters
An accurate running count of what’s left on the shelf affects decisions that happen before a project even starts, not just bookkeeping after the fact. Two situations come up repeatedly in a workshop:
- Starting a project short: Cutting into a hide partway through a build and discovering there isn’t enough left for the remaining pieces wastes time and can force a mid-project material substitution. Knowing the exact square footage on hand before laying out a pattern avoids this.
- Reordering at the right time: Waiting until a hide runs out entirely to notice often means a delay while a new order arrives. A running count makes it possible to reorder while there’s still enough on hand to finish the current project.
Whichever method is used to track it — a notebook tally updated after each cut, a spreadsheet cell adjusted by hand, or a system that subtracts automatically — the value comes from the count actually being kept current. A manual tally works fine as long as it’s updated consistently; the risk with manual tracking isn’t the method itself, it’s the update being skipped when the workshop gets busy.
Streamlining Inventory with HideLog
We developed HideLog to serve as a unified system for these exact needs. The Leather & Material Inventory feature is designed with leather-specific fields—from tannery names to thickness in ounces—ensuring your data is granular and searchable.
By utilizing the Project Log in conjunction with your inventory, HideLog removes the update-it-yourself step described above. When you link a specific material to a project and hit the “Complete Project” button, the app automatically deducts the quantity used from your stock, and that same link becomes the basis for material cost calculation. This integration ensures that your “stash” stays an accurate reflection of your physical workshop without a separate manual recount.

Summary
Transitioning from mental estimates to a structured recording system prevents the confusion of a scattered stash. By capturing essential fields—such as tannery, thickness, and unit price—and keeping the remaining quantity current, whether by hand or through a system that subtracts it automatically, makers can maintain an honest inventory, avoid starting a project short on materials, and reorder before a hide runs out entirely.
