Each thread spool is approximately 400 yards / 365 metres long and they come in a range of 12 different colours. You can purchase them individually or as a set.

These threads have been made from 30-weight corespun high quality polyester. But what does that even mean? It means it is a strong yet soft, all-purpose sewing thread which is suitable for both hand and machine sewing as well as quilting, crafting and mending.

These are part of our own range of threads, which we have worked closely with the manufacturers to ensure that each thread in our range has the same high quality while still being affordable.

What makes a good polyester sewing thread?

  • Strength & Durability

Not only does a thread need enough strength to sew smoothly without breakage interruptions, it must also be strong enough to literally hold everything together once it’s been stitched in place. Polyester is inherently stronger than natural fibres like cotton or silk threads, but the quality of the polyester used and how they are spun also influence the strength. These threads have been corespun which is a technique of using a core fibre which is the central support then wrapping the other fibres around this. This makes it less likely that the threads will fray or break while being sewn or once they are being placed under tension while your sewing creation is being used or worn.

  • Stitchability

How well the thread stitches can make a big difference to a project. Everyone wants pretty evenly spaced professional-looking stitches regardless of the fabric they are sewing with. The strength of these threads means you are less likely to experience breakages while sewing, but also the way they have been spun with the higher quality polyester means that you will experience less fraying than with some other polyester threads – this means less fluff coming off inside your sewing machine which also means a reduction in skipped stitches and birds-nest-like thread messes.

The corespun technique also helps threads recover better from stretching stresses which makes them a great choice for both stretch and non stretch fabrics. – Just remember to use a stretch stitch for those stretchy fabrics when you sew them!

  • Colour Fastness

These polyester threads don’t just start off as bright and colourful. They have been tested to make sure that they hold their colour well even after many washes.

  • Certifications & Product Safety

These threads have been certified to OEKO-TEX STANDARD 100. This means that the threads are tested at every stage of production by an independent lab every year to make sure that the threads do not contain any materials or chemicals which could be considered as harmful to health.


Should I sew with polyester or cotton thread?

Both thread types have their strengths and weaknesses. Polyester thread is stronger and longer lasting. It is more durable not only because it is harder to break in the first place but also because man-made fibres tend to break down over time at a slower rate than natural fibres. So we would recommend using polyester thread for any projects that need more structural strength, or those that will be strained at the seams more often.

Although polyester sewing threads can be used with natural fibres like cotton, silk or wool, threads work best when they are matched to their own fabric type, so we would suggest using polyester thread whenever you are sewing any synthetic-based fabrics like polyurethane laminate fabric, polyester, scuba, nylon, satin, organza, georgette, leatherette, microfibre etc. However you may need a heavy-duty thread if you are sewing thick synthetic fabrics.

Polyester has a lower melting point than cotton, so we advise choosing cotton over polyester thread if you are making anything that is likely to come into contact with higher temperatures. That includes sewing projects like microwave heat packs, hot water bottle covers, oven gloves, table mats or similar.
