Serger thread is a type of thread that is specifically designed for use with sergers, also known as overlock machines. This thread is typically made from high-quality materials that are strong and durable, allowing it to withstand the high speeds and tension of the serging process. Unlike regular sewing thread, serger thread is typically thinner and stronger, allowing it to create tight, secure seams that are ideal for finishing edges and hems. Available in a wide range of colors and finishes, serger thread is an essential tool for anyone who wants to achieve a professional-looking finish on their sewing projects.

Frequently Asked Questions (FAQs)
1. What kind of thread do you use for serger?
For sergers, cone thread is commonly used. Cone thread, available in polyester or cotton, is versatile and suitable for seaming, finishing edges, and other serging tasks. It comes in larger quantities compared to regular machine thread due to the high thread usage in sergers.
2. What is the difference between serger thread and regular sewing thread?
The main difference between serger thread and regular sewing thread is strength. Serger thread is generally weaker and sometimes has only two plies, while regular sewing thread usually has three plies. In case of urgency, regular sewing thread can be used in a serger, especially thinner threads like Mettler or Guttermann.
3. Can I use regular thread in a serger?
In a pinch for color matching, regular spools of sewing thread can be used in a serger. Thinner threads like Mettler or Guttermann are preferred in this case. However, cone thread is recommended for optimal performance and to ensure an adequate supply of thread for serging.
4. What size thread is a serger?
Sergers typically use 40 weight thread. The weight number indicates the thickness of the thread, with higher numbers representing thinner threads. However, other weights such as 50 can be purchased if necessary.
5. What is the difference between serger 3 thread and 4 thread?
The 3-thread overlock is similar to the 4-thread overlock but uses only one needle. This stitch offers more flexibility and is suitable for seaming light to medium weight fabrics or knits where a less bulky seam is desired.
6. Why do sergers use cones of thread instead of spools?
Cones of thread are preferred for sergers over traditional spools because cones can hold a larger quantity of thread. Using cones is more cost-effective as larger spools result in greater savings due to reduced winding process costs.
7. What stitch is closest to a serger?
The overlock stitch is the most commonly used stitch on sergers. The default settings for this stitch are usually indicated on the machine with a small dot next to the number four on tension dials. This stitch is versatile and can be used for various serging applications.
8. Do you have to use all 4 threads on a serger?
No, you do not have to use all 4 threads on a serger. It is possible to use 3 threads as long as both loopers are threaded. On a serger with two needles, you can leave one needle empty while ensuring both upper and lower loopers are threaded for the stitch to chain properly.
9. Is serger thread thinner than regular thread?
Yes, serger thread is generally thinner or finer than regular sewing machine thread. It is designed to avoid creating bulky seams and needs to be smooth and consistent since it passes through multiple pathways in a serger.
