You'll be surprised to know that you don't need a specialized denim jeans sewing machine to make your own jeans once or twice in a year.
I'll reveal the denim sewing secret tips later in this post so that you could easily sew jeans on your regular stitching machine.
Having said that, you will need a specialized heavy-duty denim sewing machine, if -
- You're planning to manufacture jeans in large scale for selling
- You want to make readymade looking, neatly finished denim jeans
- You do many layers of quilting and crafts with denim fabric, or
- You love to sew thick fabrics like denim, fur, jute, leather, rexin etc. on regular basis
I am making denim jeans for many years because searching for a perfect pair of jeans had become a pain.
During lockdown, it has become all the more difficult to find your preferred brands and dresses anywhere. Thus, DIY sewing became a necessity everywhere.
Thus, I have experienced jeans sewing first-hand myself and learned a lot because when I first shared my jeans sewing experience, there were no jeans tutorials available online.
Thus, I share this denim jeans sewing machine guide to help you understand denim sewing requirement and how you can get best from a jeans sewing machine.

Instead, you get a number of plastic body sewing machines, that can sew as well as design and embroider with multiple built-in stitch options.

One of the best denim sewing machine, that I liked is Singer 4423 for many reasons.
Singer 4423 machine is good for sewing denims because -

Denim Jeans Sewing Machine
Before buying a sewing machine, you must know the Difference between denim and jeans
Many people use the terms of denim and jeans interchangeably, but there is a difference in the meaning of both the words.
Denim is a type of fabric used for jeans, jeans is a type of garment.
Therefore, Jeans is a pair of pants made with denim fabric.
Now it'll be easier for you to understand what aspects make a sewing machine best for making your denim fabric jeans.
Tips to Buy Best jeans Sewing Machine
You can sew your jeans at home using a simple domestic machine but jean plants / factories use a number of different, specialized machines for making each of your branded jeans.
Based on the best practices and my jeans making experience, I am sharing the best tips to help you buy your best jeans stitching machine -
1. Your Machine Must Have a Powerful Electric Motor
Denim is a heavy fabric. So, it's most important that you must have a strong and powerful motor fixed or in-built in your sewing machine.
A strong motor can make sewing smooth and easy on toughest of fabrics.
Most of the heavy-duty machines have powerful motors for sewing tough fabrics with ultimate ease.
2. Metal bodied, heavy duty machines are best for denim
It's advised, if you sew jeans, leather or any heavy fabric on regular basis, get a sewing machine which is meant for such heavy work.
A strong metal body is important to have sturdiness while sewing multiple layers of fabric.
3. Presser foot that can be lifted a little more
Extra high pressure foot lift allows you to sew many layers of denim or heavy fabric under the presser foot easily.
You must check that your sewing machine pressure foot lifts more than usual because denim is a heavy fabric and layering makes it much thicker.
Singer sewing machines have needle adjuster that is beneficial while stitching many layers.
4. A Leveling button to adjust presser foot
You will love a leveling button on your machine to adjust the presser foot according to the thickness of your denim.
Though, not all heavy duty machines have this feature but it is excellent to have on a sewing machine, especially while working on heavy fabrics like denim.
One more thing, this feature will also reduce needles break while you sew seams of your jeans. Singer Machines have this feature.
These are Top 10 Best Automatic Sewing Machine for Beginner sewing learners. This list includes most trusted, reliable, budget stitching machines in India.
How to sew denim Jeans on Your Regular Sewing Machine
You can use a regular sewing machine and you don't need a denim jeans sewing machine for making a jeans for one time only.
If you're just going to sew one pair, a home sewing machine may handle the denim jeans if you use the right kind of needles and techniques.
Most modern sewing machines can handle occasional sewing of thick materials, like denim. But you should follow a few sewing tips.
Cutting & Stitching
1. Use right needle size
The correct needle size is the most important thing when sewing thickly woven materials like denim or canvas.
If you are sewing through thick materials such as denim, then you need a needle that is both larger and sharper than your usual universal needle.
- Needle number 70/10 – 110/18 have a thick, strong shaft and a very sharp point.
- Needle size of 14 or 16 is used for stitching thicker and harder materials like denim, canvas, duck and other heavy, tightly woven fabrics etc.
- Set a higher stitch length and lesser thread tension while sewing jeans.
2. Use good quality thread
For the thick fabric like jean or denim, you need to use thread size 30 to 50.
3. Have patience
When machine stitching thick material, sew steadily and slowly.
Guide the fabric towards the needle and gently moving the sewn pieces away from the machine.
Don't pull fabric in any direction. If you feel that the fabric is not moving, lift the pressure foot up, adjust and sew.
4. Use a new, sharp needle for sewing jeans
It's a simple sewing hack but not many people will tell you this. Because it's so simple that most of the experts assume that you'll anyway doing it regularly.
Practice using a new sharp needle and work would be beautiful.
5. Clean and dust off your machine
This is also an obvious tip that you clean your sewing machine regularly. Clear all the dust, lint, threads from shuttle and needle area.
Clean it inside out using a soft cotton fabric and a small brush (I use an old toothbrush).
Oil all the points and wipe clean surface area.
Your machine would work light and happy in general, and it would be easier to sew a jeans.
6. Use Jean-A-Ma-Jig
While using a domestic machine, it gets difficult to pass the needle through thick folds of bottom or belt
A product called Jeans-a-am-jig supports the rear of the presser foot as the front of the foot pitches up onto the seam.
This keeps the presser foot parallel to the work, so you aren’t fighting against the downward pressure of the presser bar.
7. Rub Piece Of Dry Bathing Soap On Tough Folds
Alternatively, rub a dry bathing soap piece (Lux or Lifebuoy types) on hard seam folds and your machine needle would pass through it smoothly.
I have done it a number of times and shared the video of my jeans making earlier.
How to Fix Sewing Machine tension for jeans
You should sew in a sample of fabric pieces.
If thread is lose on top, then you need to tighten the bottom tension.
If thread is lose on bottom then you need to tighten tension on top.
The way to loosen or tighten your top tension is by using a very small screw driver and on the bobbin case on the side is a small screw that can be tighten or loosen.
As for the bottom tension that is on the top part of the sewing machine but machines are different for adjusting tension,
Somewhere on the top part of the machine you will find a knob with measuring numbers next to it could be the tension indicator.
The knobs operates differently in different models.
Turn it according to the measuring number next to it or in some machines you need to push in.
How to make patch on Knee of a jeans
For machine sewing patch, you'll have to take apart at least one side of each leg of the jeans.
You'll be sewing one layer of denim to one layer of patch, and two layers of denim (to re-stitch the out seam).
You can use any sewing machine while you apply the sewing tips given above. You may choose a straight stitch, zig zag, and buttonhole.
The tip to sewing thick fabric is to sew very slowly, so the needle has time to withdraw completely before the fabric moves.
Best Denim Sewing Machines for Starting Jeans Business
You need a heavy duty machine if you're going to sew a lot of jeans or you want to start a jeans sewing business.
All the heavy duty sewing machines can sew denim jeans and other heavy fabrics nicely. In fact, an industrial table-mounted industrial machine is best for making jeans.
A single needle walking foot machine can sew through several layers of denim without breaking a needle.
It has a separate large motor that runs constantly, so the needle is at nearly full velocity when it starts moving.
You can check out an industrial triple-feed machine, which is an advanced specialized type of machine for heavy duty sewing, if you want to set up a factory.
It uses a robust hook system and a needle system that accommodates needle sizes double the diameter of an 80/12 needle.
Industrial needles also have specialty triangular points and wedge points for denim that work a lot better than the geometry of a domestic 15x1 denim needle.
The triple feed thing means that the fabric is fed by three synchronized mechanisms.
Normal feed dogs at the bottom, a synchronized rate walking foot on top, and needle feed- the needle penetrates the fabric and moves rearward, assisting the other feed systems.
They’re also big and heavy, which means more mass, more potential energy available to drive the needle through the fabric.
There’s a lot of inertia, or resistance to change in velocity, that the fabric would have to overcome to stop the machine from operating.
Types of Sewing Machines for Jeans Sewing
If you are thinking of setting up a jeans factory which is called a Plant, then you need more than the above information.
Because the jean industry uses a complicated process of sewing jeans. For this purpose, it uses a number of different sewing machines.
A commercial jean manufacturer uses 8 or more different types of machines for various sewing tasks, from the inseam, to belt loop binding, to bar tacks, and so on.
Most of the stitching is actually done on over lock and double chain stitch machines.
1. Straight stitch machine
It is a needle feed machine that allows the needle to rock forward as the machine is fed by the feeders.
This prevents stitch condensing and broken needles.
This machine is used mainly in low tech jeans sewing plants for stitching the back pockets, fly and detailed work.
Larger jean plants use twin needle lock-stitch or chain stitch for pocket hemming.
Serger is used for in and out seam finishing. This machine is a heavy duty 5 thread overlock with tractor feed.
Serger, Overlock Machine is different than Interlock Stitch. Serger / Overlocker is a special machine but you can interlock with sewing machine.
3. Union Special cylinder machine
A Union Special cylinder machine is used for hemming. This machine has a rear puller to pass each side seam without snapping needles.
4. Programmable stitchers
Back pockets are generally done on programmable stitchers with folding devices so the pockets are symmetric.
5. Singer 302 cylinder chain stitch machine
Waistbands were traditional done on Singer 302 cylinder chain stitch machines, but some jeans sewing plants use needle feed machines for this job.
6. Programmable tackers
Belt loops are attached using 42 stitch bar tackers. Many large jeans making plants use automatic belt loop inserter and programmable tackers too.
7. Rivet machine
Take a breathe. The list is not yet finished.
An air operated rivet machine is used for pocket and another one for the front
This is a short peek in the jeans making industry but that's not all.
There are many high end machines which are adding up from time to time to make jeans making a more advanced technology.
