Sewing thread: Which thread for which seam?

Sewing thread and its use: Here is the ultimate sewing thread guide that finally sheds light on the tangle of threads.

The most important things at a glance

• Sewing threads have different functions and purposes
• Not every sewing thread is suitable for all fabric types or every project
• Sewing threads are available for sewing machines, overlockers, and embroidery machines
• For a perfect stitch pattern, the sewing thread and sewing needle should match
• You will find an overview here with explanations of sewing threads and their use

What types of sewing thread are there and what are they suitable for?

There are so many threads and the selection is huge. Choosing the right one is important and should match the selected fabric and project to achieve a perfect result. We all love sewing, the best hobby in the world. That's why we always want to have good tools at our disposal. This includes the sewing machine that is right for you, a good pair of scissors, and all those practical sewing gadgets that make us enjoy our hobby even more. Often, the choice of the appropriate sewing needle and the matching thread is somewhat overlooked. Yet the needle is so important. We want to see a beautiful, perfect seam on our fabric.

With this blog post, you will learn everything you need to know to perfectly coordinate thread and material. We will focus on one manufacturer here, as there are quite a few. We are providing you with an overview from Amann Mettler.

Those who create their own things live more sustainably and consciously, and that is exactly what I want to show. I am so happy to be able to share my creativity at SewSimple. Maybe you already know me from my blog WuselGewusel or from Instagram, where I share my tutorials, knowledge, and creative adventures with you.

How do I recognize good sewing thread?

Maybe you have wondered whether expensive thread is really worth it or if the cheap stuff will do? The short answer: Quality shows at the sewing machine or at the latest on the finished seam.
You can recognize good sewing thread by the fact that it is evenly spun. This means it has no knots, lint, or thicker spots. It runs cleanly through your sewing machine without breaking or leaving lint in the hook. In addition, it feels smooth and supple, but not slippery.
When buying, look for well-known brands, because brand-name thread not only sews more pleasantly but is also of higher quality. Imagine how annoying it would be if the seams of your newly sewn sweater came undone after the first wash or the slightest strain.

We can recommend the Amann Mettler threads we have introduced to you without reservation. They have a broadly based range of sewing threads for many different applications and they also carry the OEKO-TEX® STANDARD 100 label.

How can special threads improve my sewing work?

Special threads can significantly improve your sewing work on several levels because they are tailored exactly to specific uses and fabric types. They not only add visual value to your projects but also make sewing much easier. They are essentially custom-fit partners for different fabrics, sewing techniques, and design ideas.

What is the purpose of special threads?

Maybe you are wondering why there are so many different sewing threads and thicknesses in the first place? This is because the fabrics, application possibilities, and processing options for sewing thread are so diverse. In this section, you will learn more about the functions of sewing threads.

Perfect look and effects

• Shiny or colored threads: POLY SHEEN, POLY SHEEN MULTI, or METALLIC make decorative accents and topstitching shine.
• Glow-in-the-dark or special threads: POLY GLOW add highlights that shine in the dark.
• Cotton threads: SILK-FINISH COTTON 28, 40, 50, 60 give sewing and embroidery work a 3D, sophisticated look. They look high-quality, especially with appliqués and decorative seams.

Better processing on certain fabrics

• Denim and outdoor fabrics: With DENIM DOC or XTREME PRO, robust seams can be reliably executed on heavy, durable fabrics.
• Stretchy knits: Threads like SERAFLEX or SERAFLOCK adapt to elastic fabrics, prevent thread damage, and ensure beautiful finishes.
• Fine fabrics: Threads like AMANDA or BOBBINETTE offer high tear resistance without damaging delicate fabrics like silk or batiste. SERALENE is an especially fine polyester thread that is well-suited for processing fine and extra-fine fabrics – also perfect for the overlocker.

Longevity and durability

• Hot washing: Polyester threads or specially heat-resistant cotton threads (e.g., mercerized cotton like SILK-FINISH COTTON) are well-suited for textiles that are regularly washed at high temperatures. They remain dimensionally stable and do not break.
• Dry cleaning: High-quality polyester or blended threads are chemically resistant and retain their color and stability even when cleaned with chlorine. Pure natural fibers like cotton or silk can react more sensitively to this.

Special threads like polyester thread (e.g., POLY SHEEN) or blended threads (e.g., XTREME PRO) are particularly abrasion-resistant, tear-resistant, UV-resistant, and retain their color and shine even over many years. This makes your sewing project more durable.

Facilitating special techniques

• Smocking, gathering: Elastic threads like ELASTIC allow for beautiful ruffle finishes without the fabric tearing.
• Longarm quilting: The large spools in SILK-FINISH COTTON weights 40, 50, and 60 ensure even and beautiful stitches on quilt projects.
• Optimizing bobbin thread: BOBBINETTE as a bobbin thread for embroidery work ensures a clean stitch pattern, even on lightweight or wrinkle-prone fabrics.

Which sewing thread for cotton?

There are different cotton fabrics; some are woven, others are knitted.
Woven fabric is created by crossing warp and weft threads at right angles. This makes it stable and hardly stretchy. Typical examples are cotton, linen, denim, or poplin.
Knitted fabric, on the other hand, is created by interlocking loops of thread. This gives the fabric its typical elasticity and allows it to drape wonderfully. Typical representatives are jersey, sweatshirt fabric, and knit fabrics.
Which sewing thread you ultimately use depends entirely on your sewing project and the fabric chosen for it.

What is the difference between polyester and cotton thread?

Both types of thread have their strengths.
Cotton thread is a pure natural product and is obtained from the fibers of the cotton plant. It feels soft and substantial, has a matte look, is breathable, and is pleasant on the skin. If comfort and naturalness are important to you, cotton thread is the right choice for you. However, it is not quite as robust in terms of durability and tear resistance as synthetic threads.

Polyester thread, on the other hand, is manufactured industrially from polymer-based materials. These are usually based on petroleum. That doesn't sound very romantic, but it still has advantages: The thread is particularly strong and resistant to moisture, UV light, and also wear and tear. It remains dimensionally stable and colorfast. It is a real all-rounder if you want a long-lasting result.
SERACYCLE, made from 100% recycled polyester, manages the balancing act between both threads quite well.

Is there a universal sewing thread that I can use for all projects?

Yes, there is actually what is known as universal sewing thread that you can use for most projects.
The most popular material for this is polyester because it is stable, slightly stretchy, and versatile. It works on almost all fabric types, from woven goods to jersey and blended fabrics. So, if you don't want to buy a special thread for every project, you are very well advised with SERALON. You only need special thread for a few sewing projects, such as lingerie.
In short: A good polyester thread is your sewing all-rounder, but anyone who sews a lot should definitely have a few specialists in their sewing box.

The basics of a perfect seam

Before we start the introduction to the various threads, it is worth taking a quick look at the basics. These make the difference between an uneven seam and a perfect line of stitching. Let's go!

Do you want to sew with me? The perfect combination of thread, needle, and fabric

Threads come in different thicknesses and, logically, the needle size should match. This ensures that your seams are clean, even, and stable. There are two simple ways to find out which needle fits which thread:

Way 1: Take a look at the manufacturer's website. There is usually a recommendation there as to which needle matches the respective thread thickness. This is very helpful, especially at the beginning.
Way 2: Over time, you will have the typical thread and needle combinations in your head. Then you can easily use any thread without having to research and look for long beforehand.

However, there are also rules of thumb for thread and needle sizes that will definitely help you get oriented:

• Thread thickness 120–150 (or embroidery thread thickness 40)
  → Needle size 70–80, for thick fabric up to 90
• Thread thickness 50
  → Needle size 70–80, for thick fabric up to 90
• Thread thickness 30
  → Needle size 90, with slower sewing, an 80 also works
• Thread thickness 12
  → Needle size 90–120, a Topstitch needle is ideal

Of course, the needle must also match the fabric. Fortunately, this is quite uncomplicated, because the matching descriptions are printed directly on the packaging. You can find more information about different needle points and their use here:

Upper thread tension: How to get clean seams

In addition to thread, needle, and fabric, the correct setting of your sewing machine also plays a crucial role. A point that many underestimate is the upper thread tension. Yet it is the masked hero behind even and clean seams.

It regulates how tightly the upper thread is guided during sewing. If the tension is too high, the fabric pulls together in an unsightly way. If, on the other hand, it is too low, loops form on the seam. So that your seams become nice and even, it pays to adjust the upper thread tension accordingly.

If you notice an uneven stitch pattern, check the classics first. Because if something is not right here, you can twist the tension as much as you want, and the stitch pattern still won't be clean.

How about this:

• Is your machine clean?
• Does the needle match the thread and is it neither dull nor bent?
• Was the bobbin wound correctly?
• Is everything threaded correctly?

The upper thread tension determines how much pull acts on the upper thread, and that is decisive for an even stitch pattern. Much can be compensated for just by regulating the upper thread tension. Modern sewing machines now even regulate the upper thread tension automatically. Nevertheless, it is sometimes necessary to make adjustments yourself. For example, with elastic sewing thread, like SERAFLEX.

The counterpart to this is the bobbin thread tension. This is regulated in the bobbin case and should normally not be changed by the user. Unless you are working with special techniques like gathering thread or bobbin work, a second bobbin case can make sense - you can then set the bobbin thread tension separately there.

Why do I have uneven stitches?

To ensure your seams always look neat and even, the correct needle thread tension is crucial. Sometimes, however, little stumbling blocks creep in. Don't worry, these are usually easy to fix, provided you know where the error lies. We'll show you what to look out for so your sewing projects succeed smoothly:

• Loops on top:
  Loops are forming on the top side? Then there is likely something wrong with the bobbin thread.
  → Clean the machine and check the bobbin thread.
• Loops on the bottom:
  Loops on the back? Then the problem is usually on top.
  → Re-thread, check the needle, and adjust the needle thread tension (usually downwards). If the tension is too loose, the thread can have too much slack – which also creates loops.
• Fabric puckering:
  Possible cause: Needle thread tension too high or additional stabilizer is missing – especially with decorative stitches.
• Bobbin thread is coming to the top/knot is not centered:
  Reduce needle thread tension.

This is how it should be:

• An optimal tension is achieved when the interlacing of the needle and bobbin thread – the "knot" – is located in the center between two layers of fabric.
• When embroidery and with decorative stitches, the knot should be on the back.
• Reference value: about 2/3 needle thread and 1/3 bobbin thread visible.

💡 Tip: For thick threads (weight 30 or 12), the stitches often look better if you increase the tension slightly. This releases less thread, preventing the thick thread from tangling at the bottom.

Does the bobbin thread have to be the same as the needle thread?

In short: No, the bobbin thread does not necessarily have to be the same thread as the needle thread – but there are a few important points to keep in mind.

When different threads work without issues

• Colors can be different if they are not visible on the respective side of the fabric (e.g., bobbin thread color-matched to the wrong side of the fabric).
• Quality and material may differ, as long as they run together well. Example: needle thread polyester, bobbin thread cotton → often works without issues.

When it is important for the needle and bobbin thread to be similar

• Fine or delicate fabrics (silk, chiffon, jersey): Both threads should have similar weight and elasticity so that the seam is even.
• Decorative seams (topstitching): To make the seam look neat, a heavier thread is often used on top and normal thread on the bottom — but both should be well-suited to the machine.
• Tension problems: Very different thread weights can lead to loops, uneven stitches, or thread breakage.

Recommendation

• Choose similar weights whenever possible, but the colors can differ.
• If in doubt: Use polyester all-purpose thread for both (e.g., weight 100) – this is the most problem-free option.
• For visible seams: special thread on top, normal sewing thread on the bottom.

Why does my sewing thread keep breaking?

If your sewing thread keeps breaking, there can be many causes, and it is often not the thread's fault. Here are the most frequent reasons:

• Wrong or dull needle: A needle that does not fit the fabric or thread can damage the thread.
• Too much thread tension: If the tension is set too tight, it pulls the thread too hard.
• Wrong or poor-quality thread: Cheap threads or old thread can fray, unwind unevenly, or become brittle.
• Mistakes when threading: A tiny error in the thread path can lead to tension issues.
• Wrong spool or improper winding: If the spool cannot run freely or the bobbin is wound unevenly, jerking occurs – which can also form loops or cause thread breakage.
• Dirty machine: Dust, lint, or thread remnants can block the thread path.

When changing thread, cut the thread at the top and pull the rest out through the needle.
This protects the tension discs.

Frequently asked questions and their answers

Questions about techniques and applications

• What thread weight do I need for thicker fabrics like denim or sweat fabric?
  It doesn't necessarily depend on the thread weight, but rather on the texture of your fabric.
  For denim, there is the special DENIM DOC. Thanks to the polyester core, it is robust and strong. As the name suggests, you can use it for denim, but also for canvas. A standard thread like SERALON or SERACYCLE is just as suitable.
  For sweat fabric, I recommend SERACOR or SERAFLEX. It is made of 100% polyester, which makes the thread particularly strong and durable.
• How do I change the sewing thread in my machine correctly?
  Threading and changing the sewing thread can vary depending on the machine. Some are automated, others are not, and the guidance of the bobbin thread also varies. Therefore, your machine's manual is the best source for getting everything done correctly step by step.
  If you are unsure, it's also worth stopping by a specialist dealer. They are often happy to show you personally how the thread change works.
  I’d like to share two practical tips with you:
  Make sure you remove the old threads completely, and feel free to do a few test stitches after changing.
• How do I store my sewing thread properly so it doesn't get damaged?
  To ensure your sewing threads stay nice for a long time and don't fade or fray, you should store them in a dry, dust-free, and light-protected place.
  You can find a detailed post on this, where Sabine explains how she stores her sewing thread.

Practical sewing thread tips

11. Are there thread colors that are especially recommended for beginners?
    I’m happy to share the golden rule of sewing professionals: Always choose a sewing thread one shade darker than the fabric you are sewing. Try it and be amazed!
12. How much thread should I have in stock?
    That depends heavily on how much and what kind of projects you sew. Thread doesn't have an expiration date, and if stored correctly, it lasts for many years without any issues. Personally, I’m the type of person who says, "better to have too much thread at home than too little." It would be annoying to start sewing in the evening, and suddenly, in the middle of your relaxing sewing flow, you run out of thread and the shops are already closed.
13. Can I still use old or inherited thread?
    Back when I got my first sewing machine, I also received a decent amount of sewing thread. The threads that are over 20 years old are still being used by me today and work perfectly. If it has been stored properly, you can easily continue using old thread.
    When I want to use older thread, I always do a break test first. Tear old thread and tear new thread—if they behave about the same, I’ll still use the old one. Otherwise, you’ll notice it at the latest when it keeps breaking in the machine. Then it’s straight in the bin.

Questions about safety and comfort

14. Is there a sewing thread that is particularly hard-wearing for larger sizes?
    It doesn't just depend on the size, but also on the fabric type, the seam guidance, and the stress it will be under. If a lot of fabric is being moved or the seam is under heavy strain, feel free to use a robust and high-quality thread. I can recommend the universal thread SERACOR made of polyester.
15. How do I find thread that fits my projects without it being too expensive?
    To not strain your budget, you should never skimp on the quality of the thread. Instead, get universal sewing thread in black and white. For woven fabric, SERALON is a true all-rounder. It is suitable for almost all fabrics and stitch types on the sewing machine. For knit fabric, there is the overlock thread SERACOR, which you can use for all kinds of overlock work.
16. What to do if the thread irritates my skin?
    If you have sensitive skin, reach for cotton threads. Cotton is a natural product and therefore breathable and comfortable on the skin.

Tips for more support and self-confidence

16. What do I do if I lose track and feel overwhelmed?
    My credo is: Don't let the huge range of threads overwhelm you; it's better to start small. Know the basics and then expand your knowledge step by step.
    Start by choosing a good universal thread in neutral colors like black and white. You can cover most projects with those.
    When you plan a specific project, buy the thread that matches it specifically. There is no reason to buy the whole range at once.
    Store your thread in an organized way, for example by color or thread type, and label it if necessary. This way, you can see at a glance what you have.
