What are the benefits of using larger needles in leather sewing machines?

When stepping into the world of leathercraft, one quickly realizes that not all needles are created equal. The size of the needle used in a leather sewing machine can dramatically influence the final product. Larger needles, in particular, come with a slew of benefits that can elevate your leatherwork to new heights.

Effortless Penetration

First and foremost, larger needles make the task of sewing thick, tough leather remarkably easier. Their hefty size and strength allow for effortless penetration, reducing the strain on both the machine and the operator.

Accommodates Heavier Thread

Another major advantage is that larger needles can accommodate heavier threads. Heavier threads not only give your project a robust and sturdy feel but also enhance the aesthetic appeal of your leatherwork with distinct, bold stitches.

Enhanced Durability

Moreover, larger needles are more durable and less likely to break or bend during the sewing process. This saves you the hassle of frequently replacing needles and keeps your workflow smooth and uninterrupted.

Improved Stitch Quality

Last but not least, larger needles can improve the quality of your stitches. They create larger holes that allow the thread to pass through the leather more freely, resulting in neater, more consistent stitches.

In conclusion, using larger needles in your leather sewing machine can make your sewing experience more efficient and your final product more impressive. So, next time you sit down at your leather sewing machine, consider reaching for a larger needle. You might be surprised at the difference it can make!

Are there any downsides to using larger needles in leather sewing machines?

Leather sewing machines are a boon for anyone working with this tough, resilient material. However, it’s not always a game of ‘the bigger, the better’ when it comes to needle sizes. Indeed, using larger needles in your leather sewing machine can have some downsides.

Firstly, larger needles create larger holes in the leather, which could be a problem if you’re working on a delicate or thin piece of leather. These holes might become too noticeable, detracting from the aesthetic appeal of your finished project.

Secondly, larger needles can increase the risk of damaging your leather. If the needle is too large, it might cause the leather to tear, especially along the seam where the leather is weakest.

Lastly, larger needles can also cause more wear and tear on your sewing machine. Over time, this could lead to increased maintenance and potential repairs, adding to your overhead costs.

So, while it might be tempting to use the largest needle possible in your leather sewing machine, it’s important to balance this with the potential downsides and select a needle size that is appropriate for your specific project and type of leather.

What types of leather require larger needles?

When it comes to sewing leather, the type of leather you’re working with plays a significant role in determining the size of the needle needed. Not all leathers are created equal; some are thicker and tougher, necessitating a larger needle.

Thick Leather

Thick leather, like that used for belts or saddlebags, definitely requires a larger needle. A thicker needle will be able to penetrate the leather more easily and without causing any damage to the sewing machine.

Hard Leather

Sewing hard leather, such as that used in making shoes or luggage, also requires the use of larger needles. Hard leather is often very resistant to punctures, so a larger, stronger needle is necessary to get the job done.

Layered Leather

When you’re sewing layered leather pieces together, like in a leather jacket or in upholstery, you’ll need a larger needle. The extra thickness from the layers makes it difficult for smaller needles to effectively go through.

Coarse Leather

Coarse leather, such as rawhide or some types of leather used in crafting, also requires larger needles. The texture of these leathers can make it difficult for a smaller needle to penetrate, causing potential damage to both the needle and the sewing machine.

What factors should be considered when selecting the largest size needles for a leather sewing machine?

When it comes to choosing the largest size needles for your leather sewing machine, there are a few essential factors to take into consideration. Each of them plays a significant role in ensuring the quality of your stitches and the overall longevity of your machine.

Thickness of the Leather

The thickness of the leather you’re working with is a crucial factor. Thicker leathers require larger needles to ensure sturdy and secure stitching. However, using oversized needles on thin leather can lead to punctures and damage.

Type of Leather

The type of leather you’re using also makes a difference. Soft, flexible leathers may not need as large a needle as hard, rigid ones. The needle size should be appropriate for the specific leather type to avoid causing unnecessary strain on the fabric.

Thread Size and Type

Your choice of thread size and type should coincide with your needle size. Larger needles will require heavier threads. It’s vital to ensure compatibility between your thread and needle to maintain the integrity of your stitches.

Sewing Machine Capabilities

Finally, your leather sewing machine’s specifications and capabilities should be considered. Not all machines can accommodate the largest needle sizes. Always check your machine’s manual or consult with the manufacturer before making a needle size upgrade.


When it comes to sewing leather, the size of the needle matters significantly. The largest size needle that is typically used for a leather sewing machine is a size 110/18. However, for very thick or heavy leathers, a size 120/19 might be necessary.

Remember, a larger needle leaves a larger hole in the material. Thus, it’s crucial to strike a balance between a needle that’s large enough to handle the leather’s thickness, versus one that won’t leave overly large puncture marks.

When in doubt, always test on a scrap piece of leather first. And remember, the right needle can make all the difference in your leatherworking project. Happy sewing! You may read also How To Hem Shorts With Sewing Machine?
