In-depth information about the double needle of the double stitch sewing machine.
If you’re new to cross-stitch, this article will teach you all you need to know about double stitch needles.
To sew hems on knitted garments, the twin needle, also known as a double needle, uses two needles linked together by a single bar to generate two lines of stitching on the front and a zigzag stitch on the back.

Sizes of double-stitched needle
Let’s begin with the sizes. There are a variety of double-stitched sewing machine needles in common usage, including needles with a diameters of 1.6, 2.0, 3.0, 4.0, and 6.0 mm, respectively. Millimeters are used to measure the distance between needles. Some machines may not be able to handle the 6.0mm size.
Since the throat plate hole is too tiny to accommodate the second twin needle, you should never use 6.0mm on your machine. You’ll see that the underside of the fabric you’re sewing has a zigzag pattern due to its bobbin thread snagging both top threads as you sew.
According to tradition, two numerals are often used to signify the needle size. Each of the two numbers above corresponds to an individual needle size and the distance between the needle points. There are two 80/4.0mm needles, for example, that are 4mm apart in size.
There are six different kinds of double stitch needles.
Universal twin needles
A great all-purpose needle is the universal twin needle, which is available in a variety of sizes. Their use in woven textiles is widespread, and they are also found in certain durable knit fabrics. Although the tip of the universal needles is somewhat rounded, this enables them to smoothly glide through the weaving of knits while maintaining sufficient sharpness for weaving weaved fabrics.
Stretch double stitch needles
These twin needles for stretchy knit fabric are normally smaller in size (size 75), and they are available in two different inter-needle distances: 2.5mm and 4mm, respectively. The universal double stitch needle, on the other hand, has a more rounded tip than this needle.
Double stitch needle embroidery
When it comes to decorative stitching, double stitch needle embroidery is the best choice because of the bigger groove and eye on these needles. This method also stitches more quickly than traditional stitching methods. Additionally, it features a specially-coated eye that allows for immaculate thread flow at higher speeds than before.
Double stitch metallic needles
Metallic twin needles for double stitching; these metallic twin needles are distinguishable from the others by their bigger, specifically coated eye of 2 mm in diameter and a broad groove in the shafts that prevent thread breaking during stitching.
These needles are quite similar to a twin universal needle. With a sharp, strong point, the denim twin needle has the ability to pierce even the most difficult textiles. Furthermore, this kind of point needle penetrates multiple layers of thick material more rapidly than other types of point needles. In addition, the diameter of a twin needle for use on jeans is 100 millimeters in diameter. Making denim material will be a snap with such a thick and sharp needle in your arsenal. I can confidently state that this is also an excellent choice for sewing woven textiles.
Double stitch needle hemstitch
Hemstitch using a double stitch needle. It is basically a sort of decorative stitching that is used on tightly woven fabrics to provide visual interest to the piece.
Fit a double stitch needle into your sewing machine
Using a double-stitch needle on your sewing machine isn’t easy. To begin, turn the handwheel all the way to the right to raise the needle all the way to the top. The presser foot must be lowered or removed fully at this point.
Afterwards, release the fastening screw and remove the needle from the needle holder; then, using the flat side of the twin needle, replace the needle in the needle holder until the needle touches the stopper. Then, while still keeping the needle in place, retighten the securing screw.
Double-stitch stitching requires the use of two separate spools of thread, and both must be of the same quality in order to provide a neat and uniform stitch.
Modern sewing machines, such as Janome, Juki, and Brother, have two spool pins instead.
However, you must understand that each sewing machine is unique in its design, features, and functionality.
Instructions on how to thread the needles
It is necessary to learn how to thread the needles in your sewing machine once you have placed them there.
The first step is to thread the bobbin; in this phase, you should thread the bobbin as you would normally. You are not required to follow specific instructions in this situation.
The second step is to thread the first reel; you should now be able to correctly thread the sewing machine with the first reel. After that, run the thread through the left needle and pull it tight.
The third and last step is second reel threading; you should feed the second reel of threads into the machine, which should generally be on the right side of the twin needle needle.
In sewing, here’s how to make advantage of your double stitch needle
Pins may be placed under your hemline on the right side of your garment where you will be sewing it. Place your foot in the appropriate spot and prepare to sew. It would be beneficial to feel the edge with your fingers while sewing in order to calculate the distance to stitch from the corners. Your stitching should be near to the edge but should not extend beyond it.
Hems are typically stitched in a straight pattern, although you may experiment with zigzag or other artistic stitches if you so choose.
And now that we’ve covered the many sorts, sizes, as well as how to install, thread, and operate the needle, let’s move on. Let’s go on to the next step by offering you.
Tips for a quick and easy double stitch sewing adventure
Double stitch needle sewing is prone to tunneling. Here’s what you can do to make sure it doesn’t happen again.
You may experiment with different needle tensions and stitch lengths on pieces of fabric until you get the results you want. Don’t be frightened to keep going until you achieve your goal.
A stabilizer might help if you’re still having difficulties tunneling.
Place a washable or tearable stabilizer beneath the fabric while stitching, then remove it after the project is complete. Make cautious not to stretch the fabric while removing a tearaway stabilizer.
Alternatively, you may add weight and thickness to the hem by adding a piece of hemming tape below it. Alternatively, 1cm strips of double-sided interfacing may be used if hemming tapes are not readily available.
It’s also possible that the cloth you’re working with is becoming stretched out.
You should experiment with awl-feeding the top layer. Sewing over the cloth while gently nudging the top surface with an awl or similar long and sharp instrument is a common and effective method that relies on rhythmic movements. Because you’ll be synchronizing numerous things at once, you’ll need a fair amount of talent to pull it out.
Using your walking foot is an additional technique to consider. A walking foot achieves the same goal as the awl method because it feeds the upper and bottom layers more evenly than a typical presser foot.
Another option is to use a stabilizer, which, regardless of how elastic your fabric is, will make it lay level and flat without any wobbling.
The popping seams are the next possible problem. However, a simple fix is all that is required. Twin-needle stitching provides more flexibility simply by shortening the stitch length.
As a last complication, you may find skipped stitches while working with a double stitch needle. Admit it, it’s not nice, yet it happens all the time. The good news is that there are a number of ways you may attempt to fix this issue.
There are twin-needle stretch knit ballpoints available for your convenience. Snippet-free knitting may be achieved thanks to a ballpoint tip’s ability to pierce knit fabrics. Flattens out crooked or bumpy surfaces as well.
When sewing over thick seams with the presser foot lifted, skipped stitches are more likely to occur. These ways are available to you at your leisure.
Make a small snip in the seam allowance and then slide it the other way around. It’s going to straighten up the surface.
Next, use a rubber mallet to gently pound the seams to remove any extra volume and smooth down the seams. There are areas where cutting alone will not enough, and this is the best solution.
Stitch across uneven surfaces using a hump-jumper placed behind the presser foot to keep it flat.
Frequently Asked Questions (FAQ’s)
What is a double-stitched sewing machine?
A double needle lockstitch machine functions in the same manner as a single needle machine, but it utilizes two needles and two bobbins instead of just one. The end product is two parallel rows of lockstitch. The technique of stitching done using twin needles is sometimes referred to as double needle stitching.
Is there a sewing machine that can accommodate a twin needle?
If your sewing machine is capable of stitching in both a straight line and a zigzag pattern, then the answer is “Yes.” If a sewing machine is only capable of a straight stitch, then you cannot use a double needle with it.
What is the understanding of double needle stitching?
In its most basic form, a twin needle (also known as a double needle) consists of two needles that are joined to a single shank. Because one is a hair shorter than the other, your bobbin will be able to successfully collect the thread from either needle. That bobbin is really ingenious! Similar to ordinary needles, twin needles are available in a range of different diameters.
Is a single stitch or a double stitch more effective?
Even if you catch it on anything or something occurs to the hem, the thread will remain in place because of this. The more modern form of the double stitch, which is also faster, does not accomplish this and may unravel all the way through if it is damaged. The single stitch is an imitation of the backstitch, which is the most lasting of all stitches.
What is the difference between a single sewing machine and a double sewing machine?
This kind of machine often encompasses two distinct subcategories: Lockstitching machines that employ just a single needle are called single needle machines. A double-needle lockstitch machine has two needles that are attached to a single shank. This produces two parallel rows on the front of the cloth while the back of the fabric has a zigzag stitch.
Should I use a double needle?
Fabrics that have a propensity to fray, such as cotton gauze and silk blouses, are the most typical candidates for the use of double stitching. It is essential to utilize this seam when working with fabrics that are susceptible to being damaged, such as lace curtains that are fragile or chiffon skirts that are quickly ripped.
