After doing chain stitch on the machine, I wouldn’t stop experimenting. So my next stop is a sewing machine lockstitch. And trust me, it’s way easier than you might think! Once you get the hang of it, it feels like second nature.
Here is how it works,
To sew a lockstitch on a sewing machine, simply set your machine to the straight stitch setting, ensure both threads are threaded properly, and sew in a straight line to create interlocking stitches.
That’s the glance of it. There is more to the technique. Let’s get into it.
Main facts:
- A lockstitch is where the top thread and the bobbin thread interlock inside the fabric, creating a strong.
- Lockstitch and straight stitch may look similar, but only a lockstitch interlocks the threads. A straight stitch just moves the thread straight through without locking it.
- With a lockstitch, the machine does all the work

What Is A Lockstitch On A Sewing Machine?
A lockstitch is a stitch that interlocks the top and bottom threads to form a strong, secure stitch. The top thread forms a loop that the bottom thread (bobbin thread) catches.
It pulls it through the fabric to create a tight, even stitch. It’s often used for general sewing, seams, and hemming because it’s neat, durable, and doesn’t unravel easily. It looks like a straight line, so people often confuse it with straight stitch and backstitch.
But is it true? Not really!
What Is The Difference Between Lockstitch And Straight Stitch?
Both look kinda the same from afar, but they differ. For example,
A lockstitch is when the top and bottom threads interlock to create a strong stitch. A straight stitch is just a simple, continuous line of stitching where the thread goes straight through the fabric
But it doesn’t interlock. Straight stitches are good for quick sewing, but lock stitches are stronger for longer-lasting seams.
What Is The Difference Between A Backstitch And A Lockstitch?
Now let’s clear out the confusion of backstitch.
A backstitch is a hand-sewn stitch where you go back over your previous stitches to ensure the seam is secure.
A lockstitch, though, is a machine stitch where the top and bottom threads lock inside the fabric.
Sewing Machine Lockstitch Mechanism
The beauty of machine stitch is that you don’t have to do anything. You just need to press a switch, and the machine will do the work. Here is how the machine works for lock stitch,
Setting Up the Machine
I make machine adjustment properly, thread. I guide the top thread through the machine and into the needle, then load the bobbin underneath.
Getting this part right makes the stitching smooth and frustration-free later on.
Dropping the Needle
Once everything’s ready, I gently press the foot pedal. The needle glides down through the fabric, carrying the top thread with it.
At this moment, the stitch begins to happen underneath the fabric. See? So much hassle-free, right?
Forming the Loop
As the needle reaches its lowest point, it naturally forms a small loop with the top thread. I don’t have to do anything special here.
The machine does it automatically. This tiny loop is the beginning of every strong lockstitch.
Catching the Bobbin Thread
Right after the loop forms, the bobbin hook swings into action. It grabs the bobbin thread from underneath and pulls it right through the loop made by the top thread.
It’s like a little handshake between the two threads, working together to lock in place.
Locking the Threads
As the needle starts to rise again, the top and bobbin threads twist and lock neatly inside the fabric layers.
This is the real strength of the lockstitch. The two threads securing each stitch from both sides.
Moving the Fabric Along
While the threads are busy locking, the feed dogs under the fabric lift up and pull the fabric forward. I just guide the fabric lightly. No pushing or pulling needed.
The machine does most of the heavy lifting, keeping my stitches even and my fabric smooth.
And if you wanna do sewing machine double lockstitch. Then you can switch the fabric both ways and stitch.
Stitching On Repeat
With each press of the pedal, the machine repeats this dance: loop, catch, lock, move.
As I watch the seam grow, it feels satisfying knowing that every stitch is strong, consistent, and made to last.
Finishing the Line
When I reach the end, I lift the needle, raise the presser foot, and snip the threads. Running my fingers over the stitches, I can feel how tightly and cleanly the fabric is held together. That’s the beauty of a lockstitch — professional-quality strength without much effort.
This can also work as a machine overlock stitch.
Can any Sewing Machine Do Lockstitch?
These questions pop to mind first. Cause the chain stitch needs a special kind of machine. Did lock stitch need it too?
But unfortunately, no! Most modern sewing machines (even basic ones) can do a lockstitch — it’s the standard stitch they’re built around!
When you sit down at almost any home sewing machine and start sewing a straight line, you’re already making a lockstitch without even thinking about it.
But of course, there are some exceptions. For example,
- Old, antique machines, like those from the mid-1800s, might use a chain stitch instead.
- Specialized machines, like coverstitch machines or sergers, don’t do a lockstitch. They create different types of stitches for stretchy fabrics or edges.
So, which machine works best for lockstitch? Well, there are a few machines actually. But the most famous ones,
- Mini Sewing Machine Lockstitch
- Singer Sewing Machine Lockstitch
- Brother Sewing Machine Lockstitch
In short:
Suppose you have a regular sewing machine, whether beginner or advanced. You’re already equipped to make strong, professional-looking lockstitches!
Frequently Asked Questions
Why is it called a “lock” stitch?
It’s called a lockstitch because the two threads literally lock together between the fabric layers with every single stitch. This locking action is what makes it so durable and hard to pull apart.
Is a lockstitch better than other stitches?
For everyday sewing? Absolutely. Lockstitch gives you strength, a clean look, and works on everything from lightweight fabrics to heavy-duty canvas. For stretch fabrics though, other stitches like zigzag or coverstitch might be better.
Do I need a special machine for a lockstitch?
Nope! Almost every basic sewing machine you buy today can do a lockstitch. It’s the default straight stitch setting on most machines.
