Why Hand-Stitching Leather Beats Machine Stitching: The Craftsmanship Behind Saddle Stitch.

Leathercraft has been around for centuries, and one of the key skills in creating beautiful, durable leather goods is the art of stitching. While modern machines can stitch leather quickly and efficiently, there’s a timeless appeal to hand-stitching, especially when it comes to items like saddles, wallets, bags, and belts. But what makes hand-stitching leather so special? And how does it differ from machine stitching in terms of strength and durability? In this blog post, we’ll explore why hand-stitching is often considered superior to machine stitching in leatherwork.

Hand-Stitching Leather: The Art of Saddle Stitch

Let’s start with one of the most iconic hand-stitching techniques in leatherworking: saddle stitching. It’s a traditional, labour-intensive method that has been used for centuries in everything from saddles to luxury bags and wallets.

What is Saddle Stitching?

Saddle stitching involves using two needles and a single length of thread to create a strong, evenly spaced stitch along the seam of your leather project. Here’s how it works:

1. Preparing the Leather: First, the leather is marked with stitch marks, traditionally done with a pricking iron. These holes are spaced evenly and are designed to ensure the stitches are aligned perfectly.

2. Threading the Needles: The thread is prepared with a special and two blunt needles are threaded onto either end of the thread.

3. Stitching the Leather: Starting from one end of the piece, the craftsman uses an awl to piece the leather at the stitch marks and passes the needles through-one side to the other. As the two needles pass each other in the middle of the piece, the craftsman casts the thread- creating a knotted effect between the leather, creating a strong, symmetrical stitch that locks into place with each stitch.

4. Tightening the Stitch: Whilst stitching, the thread is pulled tightly and evenly, ensuring that the stitches lie flat and pull the pieces of leather together. The tension of the stitch is crucial for both aesthetics and durability.

5. Finishing: Once the stitching is complete, the ends of the thread are backstitched, cut and burnt for a neat, safe and finished look.

Why Is Saddle Stitching Stronger?

Saddle stitching is often considered the gold standard of stitching in leatherworking, and here’s why:

• Strength and Durability: Each stitch in saddle stitching is locked into place by the opposing stitch on the other side of the leather. This makes the seam much stronger than a single-threaded machine stitch. If one stitch breaks, the rest of the stitches hold the seam together, preventing it from unravelling. This is why saddle stitching is often used in high-stress items like saddles, belts, and wallets that need to withstand wear and tear.

• Control: When you hand-stitch leather, you have full control over the tension and evenness of the stitches. This results in a more aesthetically pleasing finish and ensures that the seam is tight without being too tight, which can cause the leather to warp or weaken.

• Personal Touch: Hand-stitching gives a product a personalized, one-of-a-kind feel. Each stitch is made with care, and the end result shows the skill and craftsmanship of the artisan who created it.

Machine Stitching: The Speedy Alternative

Machine stitching, as the name suggests, uses a sewing machine to stitch leather instead of doing it by hand. While machine stitching has its benefits—primarily in terms of speed and efficiency—it lacks some of the charm and durability that comes with hand-stitching.

How Does Machine Stitching Work?

Machine stitching typically involves a sewing machine with a single needle and spool of thread. The machine feeds the leather through and creates a stitch by looping the thread through the leather. Here’s how the process works:

1. Setting Up the Machine: The leather is fed into the sewing machine, and the needle is threaded with a spool of thread.

3. Stitching: As the machine runs, the needle punctures the leather and feeds the thread through. The thread loops through both layers of leather, creating a stitch.

4. Finishing: Once the seam is completed, the machine finishes off the stitching with a few back stitches to prevent the seam from unravelling.

Why Is Machine Stitching Not as Strong as Hand-Stitching?

While machine stitching is quick and efficient, there are a few drawbacks when it comes to leatherwork:

• Inconsistent Tension: Unlike hand-stitching, which allows the artisan to carefully control tension, machine stitching is limited by the machine’s settings. If the tension is too loose, the stitches may not hold securely. If it’s too tight, it can cause the leather to pucker or become misshapen.

• Weaker Seams: Machine stitching doesn’t create the same locking effect as saddle stitching. In saddle stitching, the opposing stitches help keep the seam intact if one stitch breaks. However, in machine stitching, the thread is a continuous loop, and if one stitch fails, the entire seam can begin to unravel. This is especially problematic for leather items that need to withstand heavy use, like saddles or bags.

• Lack of Craftsmanship: Machine stitching can produce neat, uniform stitches quickly, but it lacks the individual attention and precision of hand-stitching. It also doesn’t provide the same visual appeal, as the stitching is often more uniform and less "organic" compared to hand-stitched seams.

Strength Test: Hand-Stitched vs. Machine-Stitched Leather

To truly understand the difference in strength between hand-stitched and machine-stitched leather, let’s take a look at some real-world strength tests.

1. Pull Test:

One common method of testing the strength of leather stitching is the pull test. By applying force to the stitched seam, we can see how well it holds up under pressure.

• Hand-Stitched Leather: When subjected to a pull test, hand-stitched leather shows remarkable resistance. The saddle stitching locks the stitches in place, meaning it can withstand high amounts of force before showing signs of weakness.

• Machine-Stitched Leather: Machine-stitched leather, while durable for light to moderate use, tends to give way much sooner under pressure. If one stitch breaks, it can lead to the entire seam unravelling.

2. Longevity Test:

Over time, leather that’s hand-stitched is likely to age better. The tension is more evenly distributed, and the locking stitch ensures the seam remains intact for longer whist the added wax gums up the stitch holes and protects the thread from the elements. Machine-stitched leather can fray or break more quickly, especially with heavy use.

Final Thoughts: The Art of Crafting with Care

While machine stitching certainly has its place—particularly for mass production and quick, functional items—when it comes to creating durable, high-quality leather goods, hand-stitching is the clear winner. The strength, longevity, and beauty of hand-stitched leather are second to none, and techniques like saddle stitching showcase the skill and craftsmanship of the artisan behind the product.

So, the next time you’re admiring a beautifully crafted leather saddle, wallet, or handbag, take a moment to appreciate the painstaking, skilled work that went into each and every stitch. It’s not just about function; it’s about creating something that will last, evolve, and stand the test of time.
