USING DOUBLE NEEDLES FOR A SEWING MACHINE
Any sewing machine sews with a double needle - this is not a function of the machine itself, but of the needle that you insert. You need to thread 2 spools of thread on top, then insert the threads into 2 eyes of the needle and sew. Since there is 1 bobbin at the bottom, the bottom line looks zigzag, and the top line looks like 2 parallel lines. It turns out beautifully when the tension of the upper threads is slightly tightened, then the seam on the knitwear turns out to be convex.
When you get the hang of it, try threading two different colors of thread up and using a double needle to make a decorative stitch, it’s very beautiful! Just be careful at the beginning, some machines make such a mistake that the width of the decorative stitch goes the entire width of the foot and the second tail of the needle risks running into the foot.
But! I want to note that any machine can use double needles, if the thread is inserted into the needle from the front. And now, I suggest you familiarize yourself with useful information on this topic, taken from various sources
The twin needle can be installed in any sewing machine with a zigzag stitch. The main thing to pay attention to before buying a twin needle is the width of the needle plate hole. The distance between the needles should not be wider than this hole. How to sew and how to use a double needle? Just like you use one needle, only with two top threads, passing both threads through one tensioner.
Twin needle sewing increases the capabilities of your machine and makes decorative and finishing stitches easier. Using a double needle for knitwear makes it possible to imitate the stitching of a flat-stitch machine. A sewing double needle is indispensable when sewing clothes with double stitching. Finishing stitches on jeans, patch pockets, details men's shirts and so on. You can stitch evenly and neatly by sewing a seam with a double needle.
How to use a double needle
How to use a double needle? Just like with a regular needle, you just need to buy a suitable double needle for your model sewing machine and thread both upper threads into two needles at the same time. Bottom thread in the bobbin will be used by both upper threads at the same time.
Twin needles are not suitable for all machines.
Double needles can sew different fabrics, but only in machines with a zigzag stitch; straight-stitch machines like Podolskaya are not intended for their use. The needle plate of these machines has one round hole, while the double needle requires a narrow and wide slot, which is used in zigzag stitch machines. In addition, additional thread guides and a stand for the second spool are required. If you are going to install a twin needle on your Chaika sewing machine, pay attention to how the needle is positioned in the hole when it is sewing a straight stitch. The needle should pass exactly in the center of the needle hole. If there is misalignment when using a double needle, it may break.
An additional creel is required for the second spool of thread.
Modern sewing Janome machines, Brother, Juki and many others have a creel for two spools of thread and paired thread feeders and thread guides, into which the upper threads are threaded separately.
Double needle installation
A double needle fits into any sewing machine, just like a regular needle. The flat of the needle (cut) should be directed back, away from you, and the round side should be directed towards you, forward. Each coil must have a separate pin (coil holder), sometimes an additional one is installed for this. If there is only one spool stand on the machine body, then a second one is included in the kit. The threads from the spools are passed through all the thread guides, including the upper thread tensioner, together, and only the lowest thread guides separate them into needles. The left thread is threaded into the left needle, the right thread into the right needle. If there is only one thread guide, like Chaika’s, then the left thread is passed through the thread guide, and the right one next to it, directly into the eye of the right needle.
What are they and their purpose
A double needle can have different distances between the needles - narrower, wider, and there are even triple needles. Different widths make it possible to choose the width of the finishing stitch and use it for design. The use of double needles is more intended for decorative seams that do not experience heavy loads.
Of course, it can be used to make finishing stitches on a pocket or flap shirt. But, we should not forget that to form a seam, a double needle uses only one thread - the bottom one, so such a seam will not be particularly strong. But, for example, for embroidering two or three parallel patterns at the same time, a double needle is simply irreplaceable. This pattern looks especially impressive if the threads are of different colors. Using double needles with a narrow gap between them, you can create an imitation of shadow in the design. Using narrow needles, I place threads on top of each other, creating a shadow effect. In addition to simple finishing stitches, double needles can be used for sewing on braid, performing elastic gathering, tucks and other operations.
Attention! Incorrectly selected double needles may break
double needle
When buying double needles in a store for your sewing machine, pay attention to the maximum width of the needle plate opening on your machine, or simply the width of the zigzag stitch on your machine. Incorrectly selected needles may break, hitting the needle plate.
In addition, before you start sewing with a double needle, watch the stitch type switch. The stitch should not be set to a zigzag or other needle offset, such as zipper stitching, etc. The double needle should only work in straight stitch mode. In any other mode, they will simply break on the needle plate of the sewing machine.
Use of double needles
Have you ever used twin needles in sewing on your sewing machine? Now you will find out how many decorative and other possibilities its use in creating clothes provides.
To use double needles you need:
Front threading
The presence of a zigzag stitch in a sewing machine.
The distance between the needles should not exceed the maximum zigzag width of your machine!
Preparatory operations.
Double needle
Install a double needle on your machine, just like a regular single needle.
If your machine has two spool holders, install the spools so that one spool thread unwinds clockwise and the other counterclockwise. This will prevent the threads from getting tangled when sewing.
If you don't have two thread guides, insert one thread into the thread guide and leave the other loose.
Thread the threads into the corresponding needles. The machine is ready to sew. I advise you to sew at minimum speed, this will also help prevent threads from tangling.
Decorative stitches (embroidery)
Does your machine have decorative stitches? Try using twin needles to embellish clothing with these stitches.
Decorative stitches
The double needle allows you to embroider two parallel designs at the same time. You can thread the upper threads in different colors.
If you use narrow needles 1.8 - 2.5 mm, the stitch patterns will overlap each other, creating a shadow effect.
For decorative stitches, use a needle size smaller than the maximum zigzag width on your machine!
Sewing on braid
Sew on the braid
Place a needle slightly smaller than the width of the braid into the needle holder and attach the satin stitch foot to the machine. This foot has a wide groove on the sole.
Set the machine controls to straight stitch and desired stitch length. Loosen the upper thread tension. Thread the ribbon through the needle hole of the foot (or under the foot).
Place the fabric under the foot, lower the needles into the fabric and sew. The braid is attached to the fabric on both sides at the same time.
Ruffles with elastic
Sewing on elastic
Wind a thin sewing elastic band (like Hungarian) onto the bobbin. The upper threads must match the fabric and match the color.
Set the stitch length to 2-2.5 mm and sew with a straight stitch.
An elastic band tucked into the shuttle mechanism will create thin fabric uniform assemblies. Admire how the application similar technology decorated the blouse.
Raised tucks
Relief tucks on fabric
For the following embellishments you will need a special foot for raised tucks. The foot has grooves on the sole into which the fabric is pulled during sewing, resulting in a raised fold.
Different pleat sizes require different presser feet. The wider and deeper the grooves, the more voluminous the relief can be obtained. Many parallel grooves on the foot allow you to lay reliefs that are even relative to each other.
The foot with 7 grooves is designed for small pintucks and is used on light fabrics.
A foot with 5 deep grooves is used for sewing on medium fabrics and allows you to make larger pintucks. This foot can also be used for sewing in cord.
Raised tucks
To make reliefs on light fabrics, it is recommended to use needles with a width of 1.6 - 2 mm; on medium tissues, needles 2.5 - 3 mm; and needles 4 mm or more on medium and heavy fabrics.
When stitching pintucks, the upper thread tension regulator should be set to 7-9, that is, to the maximum.
When decorating fabric with reliefs, keep in mind that the consumption will be higher.
Raised tucks
It is very important to perform the first tuck exactly, since the evenness of subsequent ones will depend on this. Therefore, draw the first line on the fabric and only then place a tuck along it.
It is advisable to first make reliefs on the larger part, then apply the pattern over the part and mark the cut lines.
Embossed tucksRelief tucks
For wide stitching of reliefs, use a quilting guide.
Reliefs can be both decorative and serve as darts.
See how you can decorate a summer blouse with raised tucks. Use embossed tucks to decorate underwear, children's clothing, blouses, and summer tops.
Reliefs on fleece
raised tucks
How much time do you spend knitting a sweater? Try knitting a sweater in one day using a double needle. Believe me, it's very simple and fast!
For such reliefs as in the photo, you will need fleece and a double needle of at least 5 mm. Such reliefs will look beautiful on velvet.
Reliefs with cord
reliefs with cord
To sew in the cord, use a double needle of such a width (the distance between the needles) that the cord passes freely between the needles.
Install any foot suitable for sewing in cord: a foot for sewing on beads or a foot for large embossed pintucks.
Reliefs with cord
Using a chalk or disappearing marker, draw a straight or curly line on the fabric where you want to add cord trim.
Pin the end of the cord to the beginning of the line on the wrong side of the fabric.
Place the fabric with the cord under the foot, make sure that the cord fits exactly between the needles and start sewing with a straight stitch following the line drawn on the fabric.
This is what the “reliefs with cord” trim on a blouse looks like. And these figured reliefs are made on transparent fabric with a backing of cords in a contrasting color.
Sewing knitwear
knitwear
To sew knitwear, use special needles for sewing knitwear with a width of 4-5 mm.
In the photo, the hem was made with a 4 mm needle. A double straight stitch is visible on the front side, and a zigzag stitch on the back side, which allows for stretching. knitted fabric. This stitch imitates sewing on an overlocker.
Knitwear
Set your machine to the straight stitch and desired stitch length.
Fold the edge of the knitted product, lay a stitch along the front side at the same distance from the fold.
Carefully trim the allowance close to the zigzag.
Sample stitches using a double needle were made on a Janome sewing machine model My Excel 23X. This machine has a maximum zigzag width of 6.5 mm.

For many beginning needlewomen, sewing with a double needle causes real stupor, because what is obtained at first is far from ideal. Today I will show you how to set up your assistant so that the seam is beautiful, elastic and not tight.
First, let's refuel the machine. We will place the second spool on an additional rod and pull the threads from both spools as one through all the necessary slots. Next we will separate the threads. We will thread one into the needle, passing it through the thread guide, and the second, bypassing it. Set the stitch length to 3.5 mm.
Let's try stitching with standard settings. We get a beautiful stitch from the face, and from the inside we get strongly elongated loops of the upper thread and a lower thread pulled almost into a straight line.
Logic dictates that the upper thread tension should be increased. Let's try. We increase it by one division and try to flash it. We get the same thing, maybe even worse.
This is the same mistake that many make. The loops on the wrong side are not because the top thread is loose, but because the bottom thread is too tight!
Let's fix it! Unscrew the needle plate, remove it and take out the bobbin holder. (It can be easily reached by hand; I needed tweezers so that my fingers wouldn’t block anything in the photo.) By the way, once you’ve opened the inside of the car, clean it thoroughly; fuzz and dust have probably accumulated there. ;)
We reached the bobbin case and saw that there were two screws on it. We don't need the right one, with a cross notch. It secures the tension plate and should never be touched! But the left screw with a flat slot is precisely designed to adjust the tension. To work we need a small screwdriver.
Note for yourself the initial position of the screw in the direction of the slot (i.e. the place on the body where the notch on the screw is directed, I have a red dot there). At first, I simply scratched a notch on the body to return the screw to its previous position with millimeter precision. Noted? Now use a screwdriver to turn the screw counterclockwise a third of a turn (I have this position marked with a green dot). Usually this is enough. We put the bobbin holder in place and tighten the needle plate.
Let's try to flash it. Sample line No. 3. Much better already! The loops from the top threads became smaller, and the bottom thread began to fit in an obvious zigzag. In principle, you can already sew like this. But I want more.))))
You can try tightening the upper thread again. And then we get the line on sample No. 4. Better? Not at all!
Then I take out the bobbin holder again and loosen the lower thread a little more. I receive sample No. 5. Hooray! Just what you need!We draw conclusions: when sewing with a double needle, the main adjustment is made not by the upper thread tension wheel, but by the screw on the bobbin holder. No matter how many times we tried to adjust the upper thread, it did not give any result other than pulling the stitches together into a roller. It may seem that this setup is complicated and time-consuming. At first, yes, but then habit and experience will turn it into a matter of seconds. And, you see, the beautiful line is worth it!
By the way, look, from the face all five samples look quite presentable.))))
Well, now you also know how to make beautiful stitching with a double needle. Like this, for example:
Good luck to everyone, obedient fabrics and precise settings! See you again soon - I'll bring a tracksuit for my first-grader.))))
A double needle is very helpful and reduces sewing time. Finishing stitches using such a needle are noticeably faster and, most importantly, smoother. When sewing denim products, it is simply irreplaceable, because double stitching is often used in these products.
Double needles, just like regular ones, are produced for different types fabrics. It is clear that if you are going to sew denim– you need to buy the appropriate needle.
Among other things, a double needle helps you work with knitwear at home. If you don’t have a flat-stitch machine, a double needle will help you out. Appearance The stitching on the front side will be exactly the same as if you made it on a cover stitch, but on the back you will get a zigzag stitch. This type of stitching using a double needle is very elastic, which is very important when sewing knitwear. You should not sew knitwear using a regular stitch; it will definitely tear when stretched at the most inopportune moment.
Buying a double needle for a sewing machine is not a problem; as a rule, the same needle can be suitable for different brands of sewing machines. Usually difficulties arise with installing the needle on the machine and threading the thread. Let's dwell on this in more detail.
You will need two spools of thread. Usually, household sewing machines have another place where you can place the second spool; if you haven’t found one, then you need to come up with some kind of device on which this spool will be attached; a tall mug in which you can place the second spool often helps.
After the coils have found their place, you can proceed to refueling the machine. In general, threading is no different from regular threading, you simply make the same movements that you do during normal threading, the only difference is that you pull both threads from the spools at once. The thread from the left spool should go into the left needle, and the thread from the right spool should go into the right. Now you can start sewing. 
Methods of using double needles for a sewing machine. Any sewing machine sews with a double needle - this is not a function of the machine itself, but of the needle that you insert. You need to thread 2 spools of thread on top, then insert the threads into 2 eyes of the needle and sew.

Sewing knitwear 
To sew knitwear, use special needles for sewing knitwear with a width of 4-5 mm.
In the photo, the hem was made with a 4 mm needle. On the front side you can see a double straight stitch, on the reverse side there is a “zigzag” stitch, which allows the knitted fabric to stretch. This stitch imitates sewing on an overlocker.
Set your machine to the straight stitch and desired stitch length.
Fold the edge of the knitted product, lay a stitch along the front side at the same distance from the fold.
Carefully trim the seam allowance close to the zigzag.
Sample stitches using a double needle were made on a Janome sewing machine model My Excel 23X. This machine has a maximum zigzag width of 6.5 mm.
To simplify and speed up the process of sewing on a sewing machine, many additional accessories are available. One of them is the double needle. This is a special removable accessory for the machine, which contains two needles at once and allows you to make two parallel lines, which are displayed on the front side.
And on the wrong side you get a beautiful zigzag stripe. As a result, you can get a beautiful elastic seam, which is often used when processing the bottom of products. Buying this tool is an excellent alternative for owners of machines without an overlocker. Let’s figure out how to properly sew on a sewing machine using the “double needle” tool.
First, it should be noted that not every machine is designed to use this model of tool. It is important that the device can perform a zigzag seam.
Some modern devices are initially designed for its installation, and already in their design have two racks for working threads. When choosing such a tool, it is necessary to take into account the design aspects of the device itself, since the gap between the needles should not exceed the width of the hole for them. In order not to manually measure the distance, you can see the instructions where it is indicated maximum possible zigzag width
. It is this parameter that will determine the purchase.
- Thus, we can highlight the main points without which it is impossible to use a double needle:
- The device provides for a zigzag seam;
- the gap should not exceed the maximum possible width of the zigzag stitch;
filling type - front. It is worth mentioning separately. When performing this, it is important not to pull the upper working threads too tightly, since the only lower thread is secured simultaneously by the two upper ones. Incorrect tension can cause rupture.
Types of needles
According to their intended use, double needles can be divided into the following groups:
- universal devices that are suitable for any fabric;
- jeans– this model is intended for use when sewing thick fabrics, such as jeans;
- super stretch used when sewing knitwear, its peculiarity is the rounded tip, which does not pierce like sewed, but carefully pushes the threads apart.
The numbers of such needles have a standard numbering. When marking, two numbers are indicated separated by a fraction: the first indicates the diameter, and the second the gap between them.
Installation
The installation of such a device is no different technically from the placement of a traditional needle. It is worth remembering that the cut should be located at the back, and the round side should be facing the seamstress. It is best if each coil has separate holder, but if this is not the case, then you can do as shown in the image.
When threading, the actions are no different from regular sewing. Simply, when passing through each hole and thread guide holder, you should do this for two threads at once. But you will need to separate the threads before the last thread guides, and then thread them into the eyes of the double device. Some models have only one lower thread guide. In this case, the left thread is passed through it, and the right one goes next to it and is threaded directly into the eye.
When working, you should monitor the position of the sewing mode switch. A double needle is used exclusively in straight stitch mode. If you install a seam with an offset, for example, a zigzag, the needle will simply break on the plate.
It is best to place the spools of thread in such a way that one unwinds clockwise, and the other counterclockwise.
This will protect the threads from tangling while working. Using the minimum speed will also prevent them from getting confused.
Application options
Many people think that the use of the device in question is limited only to the stitching for finishing and hemming, which involves two straight lines running in parallel. But this is far from true. Thanks to this tool and the capabilities of the sewing machine itself, you can make a huge number of not only decorative, but also useful stitches.
If the machine involves making decorative seams, then you can always try original stitches for decoration, which will look beautiful, especially if made in various colors. The tool in question is no less useful when embroidering, because it allows you to immediately embroider identical designs parallel to each other.
Sew on the braid
It is very convenient to use such a device to sew on braid. To do this, you will need to choose a model that is slightly narrower than the finishing tape itself. Thanks to the even, parallel double seam, the braid will lie nice and even.
Ruffles with elastic
It also makes it much easier to assemble the fabric when using this seam for the elastic. You should wind a thin elastic band onto the bobbin of the machine, and use threads that match the material as a working thread. Now you can start sewing. It is best to set the pitch to 2-2.5 mm when performing such an assembly. Due to the fact that the elastic is placed in the shuttle mechanism, you will get a uniform and beautiful assembly on the material.
Such decorative patterns can also be made using the tool in question. True, this requires special pintuck foot. It differs from the standard one in that it has special grooves on the sole, which lift the material while the work is being done. When doing this type of stitching, the pattern will be influenced by the number of reliefs on the foot itself and their depth. The larger they are, the more embossed the material will be.
It is worth remembering that the thread tension regulator should be set to maximum. At the same time, the material consumption when designing the specified pattern will increase significantly.
It is worth understanding that the beauty of the relief of the entire pattern will depend on the accuracy of the first tuck. Such reliefs can be used as simple decor or for neat design of recesses.
Reliefs with cord
To perform this operation, you should take foot for making a raised tuck or sewing in beads. In the place where the cord will be located, it is worth drawing a line with chalk or a disappearing felt-tip pen. The cord should be pinned from the wrong side. Then the material of the product is placed under the foot so that the cord is between the needles. Now you can start sewing.
The twin sewing machine needle is ideal for hemming knitwear. When performing such an operation, it is best to use zigzag foot or satin stitch. Parallel stitches are laid from the front side, while it is worth leaving a small edge free, which will subsequently be cut off near the very edge of the completed stitch.
Thus, a seamstress whose machine supports the use of a double needle must have such a component in her arsenal.
