Choosing the right sewing thread types is just as important as choosing the right fabric, needle, and sewing machine. The thread you use can affect the strength of your seams, the appearance of your stitches, the durability of your garment, and even how comfortably the finished clothing wears.
Whether you are a beginner learning to sew, a professional tailor making custom outfits, or a fashion designer producing garments for customers, understanding sewing thread will help you achieve cleaner, stronger, and more professional results.
In this guide, we will explore the four common sewing thread types: polyester, cotton, nylon, and silk, their best uses for different fabrics, and how to choose the right thread thickness for your project.
Understanding the four main types of sewing thread
1. Polyester thread
Polyester thread is strong, versatile, and resistant to shrinking, stretching, and many everyday forms of wear. It generally retains its colour well and has a slight amount of stretch, making it suitable for many modern garments.
Best for:
- Ankara, cotton blends, and polyester fabrics
- Chiffon and many lightweight synthetics, when paired with a fine thread and needle
- Knitwear and stretch garments when the stitch is suitable for stretch
- Everyday clothing, uniforms, and household sewing
It is durable, widely available, and suitable for most general-purpose sewing machines.
Ordinary polyester thread may not be the best choice for every professional application, such as very high-temperature pressing or projects requiring a traditional natural-fibre finish.
Different sewing thread types have different properties, strengths, and applications. For more technical information about thread selection and performance, read this helpful guide to sewing thread types and properties from Coats, a global sewing thread manufacturer.
2. Cotton thread
Cotton thread is made from natural fibres and is valued for its matte finish and compatibility with many natural fabrics. It is particularly useful when you want a traditional, matte stitch.
Best for:
- Cotton fabrics and lightweight quilting cotton
- Quilting and patchwork
- Traditional garments and cotton embroidery
- Some heirloom sewing projects
It has a natural-fibre appearance, minimal synthetic stretch, and good heat tolerance compared with many synthetic threads.
Cotton thread can have lower abrasion resistance than good-quality polyester and may shrink or weaken under certain conditions. Choose the right grade for heavy-duty work.
3. Nylon thread
Nylon thread is known for its high strength, abrasion resistance, and flexibility. It is commonly used for demanding sewing jobs where seams experience friction or repeated stress.
Best for:
- Bags, backpacks, and luggage
- Upholstery and some leather goods
- Outdoor equipment and accessories
- Heavy-duty applications requiring a suitable nylon thread
It is strong, flexible, and resistant to wear.
Nylon can be sensitive to heat, depending on its type. It is not automatically the best thread for every heavy fabric, and ordinary nylon thread should not be confused with specialist bonded nylon thread.
For industrial applications, match the thread specification to the machine, needle, material, and expected load.
4. Silk thread
Silk thread is smooth, fine, and often prized for its elegant finish. It is especially useful in delicate sewing where you want stitches to blend into the fabric without creating unnecessary bulk.
Best for:
- Silk fabrics and fine luxury garments
- Satin and delicate woven fabrics
- Couture sewing and fine hand stitching
- Some tailoring, basting, and specialist finishing work
It has a smooth texture, a refined finish, and suitability for many delicate fabrics.
Silk thread is generally more expensive and may be harder to find than polyester or cotton. Use a suitable thread size and needle to avoid damaging fine fabric.
Silk thread is not the same as polyester thread marketed with a silky sheen.
Which sewing thread is best for different fabrics?
The best thread depends on the fabric’s fibre content, thickness, weave, stretch, and intended use. The following table is a practical starting point for tailors and fashion designers.
| Fabric | My thread Recommendation | Why it works |
|---|---|---|
| Ankara or wax print | All-purpose polyester | Durable and best suited for everyday garment construction |
| Cotton poplin | Polyester or cotton | Both can produce neat seams; choose based on finish and project needs |
| Denim | Strong polyester or specialist jeans thread | Handles the demands of thicker seams |
| Chiffon | Fine polyester or silk | Reduces visible stitch bulk and helps preserve delicate fabric |
| Satin | Fine polyester or silk | Produces a neat finish on smooth, lightweight fabric |
| Lace | Fine polyester or silk | Helps preserve delicate details and minimise bulky stitches |
| Aso-oke | Strong polyester, selected to suit the fabric | Often appropriate for garment construction, depending on the weave and thickness |
| Jersey and knit fabrics | Polyester or stretch-compatible thread | Works well when combined with a stretch-appropriate stitch |
| Wool and suiting | Polyester or suitable silk thread | Supports clean tailoring and finishing |
| Leather | Specialist polyester or bonded nylon | Designed for demanding seams; requires a suitable needle and machine |
| Canvas and heavy bags | Heavy-duty polyester or bonded nylon | Suitable for abrasion and heavier seam loads |
| Upholstery | Heavy-duty polyester or bonded nylon | Useful for furniture and other high-wear applications |
These are general recommendations, not absolute rules. For example, a lightweight Ankara blouse may need a finer thread than a heavy, multi-layered Ankara garment. Always consider the fabric’s actual thickness and the stress the finished seam will experience.
Understanding sewing thread weight
Thread weight describes the thickness or fineness of a thread, but the numbering system can be confusing because different systems use different conventions.
In many commonly used thread-numbering systems, a higher number indicates a finer thread. For example, a thread labelled 60 is generally finer than one labelled 30 in a system where the numbers represent inverse size. However, some systems use different conventions, so never compare thread numbers without checking the manufacturer’s numbering system.
Here is a practical overview of common thread sizes and their typical applications.
| Thread size | Typical use | Applications | Approximately Tex |
|---|---|---|---|
| Fine | Delicate fabrics and fine stitching | Suitable for some fine silks, chiffon, lightweight lining, and delicate finishing. Pair with an appropriately fine needle and verify that the thread is strong enough for the seam. | 8–18 |
| Light to medium | Everyday garment construction | A practical range for many blouses, dresses, shirts, cotton fabrics, and lightweight-to-medium Ankara garments. | 18–30 |
| Medium to heavy | Stronger seams and heavier garments | Useful for many trousers, workwear, denim, canvas, and decorative topstitching, provided the machine and needle can handle the thread. | 30–60 |
| Heavy-duty | Demanding industrial or specialist work | Used for certain bags, upholstery, leather goods, and heavy-duty seams. Check the manufacturer's specifications because the appropriate size varies by application. | 60 and above |
Tex is a direct measure of linear density: the mass in grams of 1,000 metres of thread. A higher Tex number means a heavier thread. It helps when different manufacturers use different numbering systems.
These Tex ranges are approximate guidance, not universal classifications. Always check the thread manufacturer’s specifications, especially for industrial machines.
How to choose the right thread weight for your project
Choosing the correct thread weight is about finding a balance between seam strength, appearance, fabric thickness, and machine performance.
1. Start with the fabric thickness.
Use a fine thread for delicate, lightweight fabrics and a stronger, heavier thread for thick materials. An excessively heavy thread can create bulky seams, while an overly fine thread may break under stress.
2. Consider the purpose of the garment.
A lightweight blouse usually doesn’t need the same thread as a pair of work trousers. A decorative stitch may call for a thicker, more visible thread, while an internal seam often benefits from a more discreet finish.
3. Match the thread to the needle.
The needle eye must be large enough for the thread to pass through smoothly. A thread that is too thick for the needle can cause friction, skipped stitches, thread breakage, and fabric damage.
4. Check the sewing machine’s capability.
Domestic machines and industrial machines can have different thread and needle limits. Heavy-duty thread may require a compatible needle, machine setup, tension adjustment, and sometimes a specialist machine.
5. Think about stretch and movement.
Knitwear and stretch garments need a thread and stitch combination that can accommodate the fabric’s movement. Polyester is a common choice, but the stitch type matters just as much.
6. Test before sewing the actual garment.
Sew a sample using the same fabric layers, thread, needle, stitch length, and machine settings you plan to use. Check the seam for puckering, skipped stitches, breakage, and excessive bulk.
Quick thread selection guide for Nigerian tailors
Here are some everyday examples for tailoring businesses and fashion designers in Nigeria.
| Project | Suggested starting point |
|---|---|
| Ankara gown | All-purpose polyester, light to medium weight |
| Senator wear | Polyester thread suited to the fabric weight |
| Agbada with multiple layers | Durable polyester and a suitable needle for the fabric and seam thickness |
| School uniforms | All-purpose polyester |
| Denim trousers | Strong polyester or suitable jeans thread |
| Bridal or evening gown | Fine polyester or silk, depending on the fabric and finish |
| Stretch leggings | Polyester thread with a suitable stretch stitch or overlock setup |
| Leather bag | Specialist polyester or bonded nylon with compatible equipment |
| Pillowcases and bedsheets | Polyester or cotton, depending on the fabric and finish |
| Upholstered furniture | Suitable heavy-duty polyester or bonded nylon |
For traditional Nigerian outfits, especially garments made from heavier woven fabrics, test the thread on the actual material before committing to the full garment. Some decorative fabrics may require a different thread for visible embroidery or embellishment than for their structural seams.
Common sewing thread mistakes to avoid
1. Using heavy thread on delicate fabric
This can create bulky seams, visible needle holes, puckering, or damage. Choose a finer thread and an appropriate needle.
2. Choosing thread based on colour alone
A perfect colour match cannot compensate for a thread that is too weak, too thick, or unsuitable for the fabric.
3. Assuming all polyester threads are identical
Polyester threads differ in strength, finish, construction, and intended application. Choose a suitable quality and specification for the job.
4. Ignoring needle and machine compatibility
The wrong combination can cause thread breakage, skipped stitches, uneven tension, and poor seam quality.
5. Using old, damaged, or poorly stored thread
Thread exposed to excessive heat, sunlight, dust, or prolonged storage may deteriorate. Inspect your thread before using it on an important project.
Frequently asked questions about sewing threads
Which sewing thread is best for beginners?
All-purpose polyester is a practical starting point because it works with many common fabrics and everyday sewing projects. As your skills develop, you can add cotton, silk, nylon, and specialist threads for specific applications.
Can I use polyester thread on cotton fabric?
Yes. All-purpose polyester is commonly used for cotton garments, including Ankara and cotton poplin. Choose the thread weight and needle according to the fabric and project.
Is cotton thread stronger than polyester thread?
Not necessarily. Strength depends on the thread’s construction, size, and quality. Polyester is often a practical choice for durable everyday seams because it generally offers good abrasion resistance and some flexibility.
What thread should I use for Ankara fabric?
All-purpose polyester is a good general choice for most Ankara garments. Use a finer thread for lightweight material and a suitable stronger thread for thicker layers or demanding seams.
What does Tex mean on a spool of thread?
Tex measures thread linear density in grams per 1,000 metres. A higher Tex number means a heavier thread, which can help you compare thread sizes across products.
Can one thread type be used for every sewing project?
No single thread is ideal for every application. All-purpose polyester covers many everyday needs, but delicate silk garments, heavy leather goods, upholstery, and stretchwear may require more specialised thread choices.
