What Thread to Use for Sewing: Three Practical Picks
What thread should you buy first?
For everyday sewing, our starting choice is a documented general-purpose polyester thread that your machine and project instructions permit. Choose cotton when the project calls for cotton, and buy decorative thread for a specific visible seam. Check the spool, fabric and needle together. Switch off and unplug before needle-area adjustments, and follow the machine manual rather than forcing an incompatible combination.
This is a desk-researched comparison of manufacturer information, not a sewing test. Our criteria are a clear intended use, identifiable fibre and size, published needle guidance, and a reason to choose the thread for the actual project. The recommendations below are editorial choices. No price, durability ranking or promise of trouble-free stitching is implied.
Which of these three threads suits your project?
These are three Gütermann products with different jobs. The table reports their current product-page specifications; it does not turn a thread maker's needle recommendation into permission for every machine.
| Pick | Documented specification | Our suggested use | Main limitation |
|---|---|---|---|
| Sew-all | 100% polyester; No. 100; universal needle NM 70–90 | First candidate for ordinary seams when the project permits general-purpose thread | Does not meet a cotton-only requirement |
| Natural Cotton C Ne 50 | 100% mercerised cotton; Ne 50/3 / No. 85; universal needle NM 70–90 | Cotton-specified patchwork or another project requiring that fibre | Cotton content alone does not establish suitability for a particular seam |
| Top Stitch | 100% polyester; No. 30; universal needle NM 100–120 | A deliberately visible decorative seam on suitable medium-to-heavy fabric | Its larger recommended needles may exceed your machine or fabric's requirements |
Our verdict: start with the first option for an unspecified everyday project, choose the second for an explicit fibre requirement, and reserve the third for a planned decorative effect. These are starting candidates, not a substitute for the pattern or equipment instructions.
Everyday seams: why choose Sew-all?
The manufacturer lists machine and hand sewing, closing seams and topstitching among its uses. That makes it our practical starting candidate when the project has no specialist thread specification. Its drawback is the same breadth: a general-purpose label cannot answer every fabric, stitch or end-use question. Check the actual project before buying a large colour assortment.
Cotton projects: why choose Natural Cotton C Ne 50?
The product page specifically lists quilting, patchwork and decorative seams. Our reason to select it is a project requirement or preference for cotton, not a claim that cotton fabric always requires cotton thread. The drawback is that this purchase settles only the fibre choice. You still need a compatible needle and an acceptable sample.
Visible detail: why choose Top Stitch?
The maker specifies this product as needle thread with Sew-all as bobbin thread. That is a product-specific combination, not a rule for every decorative thread. Choose it when the seam itself is meant to show. Its drawback is the extra compatibility check: do not buy it assuming you can put the same spool in both positions or fit the recommended needle range to any machine.
Does the fabric name decide the thread?
Make a short project card before shopping. Write the fabric as sold, what the seam must do, and any thread requirement in the instructions. “Cotton” describes a fibre; “join these patchwork pieces” describes a job. Keep both on the card.
For a straightforward woven project, use the first pick as a candidate only after checking the instructions. For cotton-specified patchwork, investigate the second. For an intentional visible seam, investigate the third and its equipment requirements. For stretch fabrics, very delicate cloth or an unfamiliar construction, ask the pattern supplier or a knowledgeable sewing retailer for a specific combination before buying.
Take a fabric offcut and the machine model with you. Ask: “Which exact product, which needle, and which instruction supports that pairing?” A usable answer should identify something you can write down. “Any strong thread” is too vague to become a repeatable purchase.
For point types and compatible needle systems, use our needle-selection guide. This article chooses the spool; that guide handles the needle decision in detail.
What do thread weight and spool numbers mean?
In Coats' numbering guide, Tex is grams per 1,000 metres: a higher Tex value means a heavier thread. English count, written Ne, works in the opposite direction, with a higher count indicating finer yarn. Ticket numbers are commercial references, and the same ticket number can represent different thread types.
Therefore, copy the entire label, including its system and any slash. A bare “50” is not enough information to compare two spools. Do not treat the three product labels above as measurements on one shared scale, or calculate a substitution from their numbers alone. Ask the manufacturer for an equivalent if the instructions name another system.
Is a bargain spool a false economy?
Price alone does not answer that question. Coats' technical bulletin identifies uniform diameter and surface finish as contributors to sewability; uneven thread can knot and jam at the needle eye. It also distinguishes fibre from construction, including spun and corespun threads. Those are reasons to seek an identifiable product, not evidence that every cheap spool is poor.
Our buying rule is to compare traceable products before comparing pack size. Record the maker, product line, fibre, labelled size and intended use. A low-priced spool that meets the project requirements is worth considering. An unlabelled bundle leaves questions unanswered even if the colours are appealing.
We have not measured lint or breakage for these products. A brand name is not our test result, and a higher shelf price does not establish better performance in your machine.
What should a small starter kit contain?
Buy for the next project, not an imagined wardrobe. Our suggested starter list is one suitable thread line in the project's required colour, the correct machine-compatible bobbin supply, and a card or envelope for the sample and spool details. Add another fibre or decorative product when a real project needs it.
Before ordering a multipack, make a simple purchase record:
- Project: what you are actually making.
- Requirement: exact thread instruction, or “not specified”.
- Candidate: full product name and label notation.
- Open question: anything the manual or retailer must resolve.
- Decision: buy one spool, investigate another candidate, or postpone.
For example, a fictional cushion project with no named thread could generate one everyday candidate. A patchwork pattern explicitly requesting cotton would generate a separate cotton candidate. This is a shopping decision, not a prediction that either sample will pass.
How do you decide whether to buy more?
Make a small sample using the intended layers and the setup allowed by your machine instructions. The Brother manual for product codes 888-N00/N02/N20/N22/N40/N42/N60, printed pages 2–3, requires unplugging for adjustments and keeping fingers away from moving parts. Use your own model's manual; stop for damage or persistent faults and seek authorised service.
Label the sample “candidate”, not “approved”, before sewing. Afterwards, record what you actually observed: the appearance on each side, any interruptions, and whether the result meets the project's stated aim. Keep observations separate from explanations. “Thread broke twice” is a record; “the thread is defective” is a diagnosis the sample alone cannot establish.
Keep the thread label with that sample. If the result is unsuitable, use the threading and tension guide rather than changing several settings at once. Follow the needle-changing guide and your manual when replacement is needed. Buy more only after you have a documented combination worth repeating.
