How to Saddle Stitch Leather by Hand

Saddle stitching is one of the strongest and most traditional methods of hand stitching leather. Used by saddlers, leatherworkers, and artisans for generations, saddle stitching creates durable seams that are ideal for belts, wallets, bags, straps, and other leathercraft projects.

Unlike machine stitching, saddle stitching uses two needles and a single length of thread to create an exceptionally strong hand-sewn stitch that will not easily unravel if damaged.

In this guide, we’ll cover:

• what saddle stitching is
• the tools you need
• how to saddle stitch leather step-by-step
• common mistakes to avoid
• the best needles and thread for leathercraft

What Is Saddle Stitching?

Saddle stitching is a traditional leather hand stitching technique where two needles are passed through the same hole from opposite directions.

This creates a locking stitch that is:

• extremely strong
• durable
• attractive
• resistant to unraveling

Because each stitch is independently locked, saddle stitching is often stronger than standard machine stitching for leather goods.

Saddle stitching is commonly used for:

• leather wallets
• belts
• bags
• watch straps
• sheaths
• saddlery
• equestrian leatherwork

Tools Needed for Saddle Stitching Leather

Before starting, you’ll need a few essential leathercraft tools.

Essential Leather Stitching Tools

1. Harness Needles

Blunt-tip saddlers harness needles are designed specifically for leather hand stitching.

Recommended:

• John James Saddlers Harness Needles

Best beginner size:

• Size 004

2. Waxed Thread

Waxed thread helps reduce friction and improves stitch durability.

Popular choices include:

• polyester waxed thread
• linen thread
• tiger thread

Thread thickness should match your stitching spacing and leather thickness.

3. Pricking Irons or Stitching Chisels

Stitching Chisels and Pricking Irons are punch tools that create evenly spaced stitching holes.

Pricking irons mark out the holes that can then be opened with a diamond leather awl.

Stitching chisels (also known as Stitching Punches or Diamond Chisels) are tools for pre-punching holes in preparation for hand stitching.

For beginners:

• Diamond stitching chisels are often easiest to use

4. Stitching Pony (or Stitching Horse)

A stitching pony holds the leather securely while stitching.

This improves:

• stitch consistency
• tension control
• speed

5. Diamond Leather Awl

Some leatherworkers use a stitching awl (also known as a Diamond Awl or Diamond Stitching Awl) to create or open holes, particularly while stitching thicker leather.

How to Saddle Stitch Leather Step-by-Step

Step 1 — Mark Your Stitch Line

Use a wing divider or stitching groover to mark a consistent stitch line along the leather edge.

This helps:

• improve appearance
• maintain even spacing
• create cleaner stitching

For most leather goods:

• 3–5 mm from the edge works well.

Step 2 — Punch the Stitching Holes

Use stitching chisels or pricking irons to create evenly spaced holes.

Keep the holes:

• straight
• evenly spaced
• angled consistently

For beginners:

• 4 mm spacing is versatile for wallets and belts.

Step 3 — Cut Your Thread

A good rule:

• use approximately 4-5 times the stitch length.

Too little thread makes stitching difficult.
Too much thread increases tangling.

Step 4 — Thread the Needles

Attach one harness needle to each end of the thread.

Most leatherworkers lock the thread onto the needle by:

1. passing the thread through the eye
2. piercing the thread tail with the needle
3. pulling tight

This helps prevent slipping while stitching.

Step 5 — Begin the Saddle Stitch

Start from one end of the stitch line.

1. Pass the first needle through the first hole
2. Centre the thread evenly
3. Pass the right-hand needle through the next hole
4. Pass the left-hand needle through the same hole from the opposite side
5. Pull both threads tight evenly

Repeat this process for each stitch.

The key is maintaining:

• even tension
• consistent angles
• smooth rhythm

Step 6 — Backstitch to Finish

At the end of the seam:

• stitch backwards 2–3 holes
• trim the thread
• melt or tap flat if using synthetic thread

This locks the stitching securely.

Best Needles for Saddle Stitching Leather

One of the most important parts of leather hand stitching is choosing the correct needle.

Professional leatherworkers often prefer:

• John James Saddlers Harness Needles

because they:

• resist bending
• have smooth polished finishes
• glide through stitching holes easily
• work well with waxed thread

For beginners:

• Size 004 is usually the best all-round option.

Best Thread for Saddle Stitching

Popular thread choices include:

Thread Type	Benefits
Polyester Waxed Thread	Strong, durable, water resistant
Linen Thread	Traditional appearance
Tiger Thread	Very strong and easy to use

Choose thread thickness based on:

• leather thickness
• stitch spacing
• project type

Common Saddle Stitching Mistakes

Uneven Stitch Tension

Pulling harder on one side creates inconsistent stitches.

Try to maintain equal tension throughout.

Crooked Stitch Holes

Misaligned holes create uneven stitching.

Use sharp stitching chisels and maintain consistent angles.

Using Sharp Sewing Needles

Leather saddle stitching requires blunt harness needles, not fabric sewing needles.

Sharp needles can damage leather fibres.

Wrong Thread Thickness

Thread that is too thick or thin for the hole spacing affects stitch appearance and durability.

Why Saddle Stitching Is Better Than Machine Stitching

Many leatherworkers prefer saddle stitching because:

• it is stronger
• easier to repair
• more traditional
• visually attractive

Machine stitching can unravel if one stitch breaks.
Saddle stitching usually remains secure even if one stitch becomes damaged.

This makes it ideal for:

• premium leather goods
• belts
• heavy-use items
• handmade products
