How Leather Is Made: From Hide to Handbag
Behind every Mel's Fashion leather bag is a remarkable journey — one that begins on Kenya's vast pastoral lands, passes through the skilled hands of tannery workers and artisan craftspeople, and ends in a product designed to last for decades. Understanding how leather is made deepens your appreciation of what you carry and helps you recognise the immense skill and craft involved.
Step 1: Hide Collection and Preservation
The process begins with raw hides — the skins of animals (in Kenya's case, primarily cattle, goats, and sheep) that are a by-product of the meat and dairy industries. Hides are collected from abattoirs and must be preserved immediately to prevent decomposition.
Two primary preservation methods are used:
- Wet salting: The hide is rubbed with salt and stacked. Salt draws moisture out and inhibits bacterial growth. Most Kenyan tanneries receive wet-salted hides.
- Dry salting / curing: The hide is salted and then dried, resulting in a stiff, board-like skin that can be stored for months before tanning.
Step 2: The Beamhouse Operations
Once hides arrive at the tannery, they go through a series of preparatory treatments collectively called beamhouse operations. These take place in large drums or pits filled with water and chemical solutions.
Soaking
Preserved hides are soaked in water to rehydrate them and remove salt, dirt, blood, and other contaminants. This can take 1–2 days.
Liming
Hides are placed in a lime (calcium hydroxide) solution that loosens and removes hair and epidermis, and begins to open up the hide's protein structure to prepare it for tanning. This process takes 1–3 days.
Fleshing
A mechanical fleshing machine removes residual subcutaneous fat and flesh from the inner side of the hide, leaving a clean skin of fairly uniform thickness.
Splitting
If needed, the hide is split into layers using a band knife. The top layer becomes full-grain or top-grain leather; the lower split is used for suede, genuine leather (grade), or bonded leather.
Deliming and Bating
Lime is removed from the hide using acidic agents (deliming), then proteolytic enzymes (bating) are applied to make the leather softer and more pliable. This step greatly influences the final feel and softness of the leather.
Step 3: Tanning — The Core Transformation
Tanning is the critical process that transforms a biodegradable animal skin into stable, durable leather. It works by permanently bonding tannin molecules to the collagen fibres in the hide, preventing putrefaction and giving leather its unique properties.
Vegetable Tanning
The oldest tanning method, using plant-based tannins from sources such as quebracho bark, mimosa, oak, and chestnuts. In Kenya, local bark sources including wattle (Acacia mearnsii) have been used traditionally. The hides are moved progressively through pits containing increasingly concentrated tannin solutions over a period of weeks to months.
Vegetable-tanned leather is firm, develops a rich patina, is biodegradable, and has a warm, natural colour. It is the preferred choice for premium, artisanal leather goods.
Chrome Tanning
The most widely used modern method, using chromium sulphate salts. Hides are tumbled in rotating drums with chrome solution for 24–48 hours. The result is leather that is softer, more water-resistant, and available in a wider range of colours. Chrome-tanned leather (called "wet blue" at this stage due to its colour) is the dominant commercial leather worldwide.
Combination Tanning
Many premium manufacturers use a combination approach — chrome tanning for initial softness, followed by re-tanning with vegetable tannins. This produces leather with the durability of vegetable-tanned and the flexibility of chrome-tanned leather.
Step 4: Wet Finishing
After tanning, the leather goes through further treatments to achieve the desired properties:
- Sammying/Wringing: Excess water is mechanically pressed out of the leather
- Splitting (if not done earlier): Leather is split to the desired thickness
- Shaving: Fine shaving machines create a uniform thickness across the entire hide
- Retanning: Additional tanning agents are applied to enhance specific properties
- Dyeing: Leather is drum-dyed with water-based dyes that penetrate the full thickness or just the surface
- Fat-liquoring: Oils and emulsifying agents are applied to lubricate the leather fibres, giving the leather its suppleness and preventing brittleness
Step 5: Drying and Conditioning
The leather is dried — either naturally by hanging, or mechanically using toggle drying (stretching and pinning the leather to frames as it dries to prevent shrinkage). After drying, the leather is conditioned and softened through mechanical staking or milling (tumbling in drums).
Step 6: Dry Finishing
The surface of the leather is now prepared for its final finish:
- Buffing/Sanding: Surface buffing removes imperfections (creating top-grain) or is not applied (leaving full-grain intact)
- Surface coating: Pigments, polymers, and waxes are sprayed or roller-applied to protect the surface and achieve the desired colour and texture
- Embossing: Heat and pressure from engraved plates can impart grain patterns (used on corrected-grain and bonded leather)
- Glazing or polishing: A final polish gives the leather its characteristic sheen
- Quality inspection: Every hide is inspected and graded before leaving the tannery
Step 7: Cutting and Crafting — The Artisan's Role
Finished leather arrives at Mel's Fashion's Nairobi workshop as large hides. Our craftspeople then:
- Inspect and grade each hide — identifying the highest-quality sections for visible exterior panels
- Create patterns and cut panels — using precision templates to cut each component of the bag
- Skive edges — thinning the leather at fold points and seams to reduce bulk
- Mark and punch holes — for stitching, hardware, and functional elements
- Apply adhesive and stitch — using high-quality thread at tight stitch counts for maximum durability
- Attach hardware — zips, clasps, D-rings, and other metal elements are fitted
- Apply edge finish — edges are burnished, painted, or folded and stitched
- Final conditioning — each finished bag is conditioned with leather oil before packaging
Kenya's Tanning Industry
Kenya has several established tanneries, particularly around Nairobi and Athi River. The Kenyan leather sector processes approximately 3–4 million hides annually, though the government has been investing in upgrading tanning capacity to add more value to raw hides that were previously exported. Mel's Fashion is proud to be part of this value chain — supporting Kenyan tanneries and Kenyan craftspeople.
Frequently Asked Questions
Q1: Is the leather-making process harmful to the environment?
Traditional chrome tanning generates chromium-containing wastewater, which requires careful treatment. Kenyan tanneries are subject to NEMA (National Environment Management Authority) regulations. Vegetable tanning is significantly more environmentally friendly. Mel's Fashion prioritises suppliers who follow responsible waste treatment practices.
Q2: How long does it take to make a leather bag from raw hide?
The complete process — from raw hide to finished bag — takes approximately 3–6 weeks. Tanning alone (vegetable method) takes 2–6 weeks. Crafting the bag, depending on complexity, takes an additional 4–20 hours of skilled artisan time.
Q3: Why is hand-cutting better than machine cutting?
Hand-cutting by an experienced artisan allows for the selection of the best sections of each hide for each panel, avoiding imperfections. Machine cutting is faster but indiscriminate — it may place a blemish on a visible panel. This is why handmade leather goods command a premium.
Q4: What makes Kenyan leather different from Italian leather?
Italian leather has centuries of refined tanning tradition and finishing techniques. Kenyan leather has equally rich tradition, with vegetable tanning in particular, plus the advantage of locally adapted cattle breeds and conditions. The main difference is in finishing techniques and international marketing — not necessarily in raw quality. Mel's Fashion is working to showcase Kenyan leather on the world stage.
Q5: Does the type of stitching matter?
Enormously. Saddle-stitching (done by hand, with two needles passing through the same holes from both sides) is far more durable than machine lock-stitching. If one thread breaks in saddle-stitching, the seam holds; if a machine stitch breaks, the whole seam can unravel. Mel's Fashion uses saddle-stitching on all structural seams.
