A sewing machine needle may be a small and relatively inexpensive part of your machine, but it can have a surprisingly big impact on the quality of your sewing and the condition of your machine.
One of the simplest ways to help prevent sewing problems — and potentially expensive damage — is to change your needle more regularly than you might think.
How Often Should You Change Your Sewing Machine Needle?
As a general rule of thumb, if you sew one complete dress, you should expect to use one needle.
However, this will vary depending on the fabric you are sewing. Thicker, heavier or more densely woven fabrics will put more strain on the needle, meaning it may need to be changed more frequently. Thinner or more loosely woven materials may allow a needle to last slightly longer.
Rather than waiting for a needle to break before replacing it, changing it regularly should be considered part of your normal sewing machine maintenance.
Why Is a Worn Needle a Problem?
Every time your needle passes through the fabric, it experiences a small amount of wear. Over time, the point of the needle can become blunt or develop a tiny burr.
You may not always be able to see this damage with the naked eye, but it can affect the way your machine sews.
A worn or damaged needle can contribute to problems such as skipped stitches, damaged fabric, broken thread and poor stitch quality. Most importantly, continuing to sew with a damaged needle increases the risk of the needle breaking inside the machine.
A Broken Needle Can Damage Your Sewing Machine
Ideally, you should never allow a needle to become so worn or damaged that it snaps while sewing.
When a needle breaks, it does not always break cleanly or harmlessly. The broken needle can strike important parts of the sewing machine, including the hook and needle plate.
Damage to these areas can then cause further sewing problems. A damaged or marked hook, for example, can catch the thread as you sew, resulting in repeated thread breakage. Damage around the needle plate or hook area can also contribute to poor stitch formation and apparent tension problems.
What began as an inexpensive needle replacement can therefore turn into a much more complicated repair.
How to Check Whether Your Needle Is Blunt
There is a simple way to check the condition of your sewing machine needle.
Remove the needle from the machine and hold it flat. Gently drag the point of the needle across the surface of your fingernail.
Slowly rotate the needle as you do this so that you check the full 360 degrees around the needle point.
A needle in good condition should move smoothly. If the needle has become blunt or developed a burr, you will often feel it catch or drag against your nail.
If you can feel any roughness, resistance or catching, replace the needle.
Don’t Wait for the Needle to Break
Sewing machine needles are consumable items. They are designed to be replaced regularly, just like many other parts that experience wear through normal use.
It can be tempting to keep using the same needle simply because it has not broken yet, but a needle does not need to be visibly damaged to cause sewing problems.
Changing your needle regularly is a quick and inexpensive way to protect your fabric, improve your stitch quality and, most importantly, help protect the internal components of your sewing machine.
So, before starting your next project, take a moment to think about the needle currently fitted to your machine. If you cannot remember the last time you changed it, there is a good chance it is time for a new one.
A fresh needle costs very little — but it could save you from a much more costly sewing machine repair.
