Best Serger Thread Cones: Threading the Needle on Serging Success

08 November 2024

Serging (or overlocking) is a key skill in sewing that gives you a professional finish to edges and seams. To get to that level of finesse you need to use the right thread. With so many options out there it can feel like threading a needle. This guide will help you navigate the world of serger threads so you can make informed decisions.

Serger Threads

Sergers are special machines that require special threads to run smoothly and produce high quality results. Unlike regular sewing machines, sergers use multiple threads to secure fabric edges so the thread needs to be strong and flexible. The best thread to use in a serger is usually lightweight and durable, reduces bulk and gives a cleaner finish. MaxiLock and SureLock are recommended serger thread brands for their durability and performance.

Serger threads come in cones not spools so you can get more and won’t run out mid project. The threads are usually made from polyester or nylon, materials known for their strength and resilience. Core spun polyester thread is particularly good because of its strength, durability and flexibility, it’s perfect for creating smooth professional seams on all types of fabrics. These fibers don’t break easily which is important when the thread is moving at high speeds.

What is serger thread and how is it different from regular sewing thread?

Serger thread is a special type of thread designed for use in serger machines. Unlike regular sewing thread, serger thread is finer and smoother which helps reduce bulk in the serged area. This is important because sergers run at high speeds and handle multiple layers of fabric at once. The finer, smoother thread ensures the seams are flat and professional looking.

Also serger thread is designed to withstand the high speed, high tension environment of serging. It’s stronger and more durable than regular sewing thread, reduces the chance of breakage during sewing. Another difference is that serger thread is wound onto large cones, called serger cone thread, so you can sew for longer without having to change thread as often. This is especially useful for big projects or continuous sewing.

What kind of thread is best for serging?

Why Polyester is King for Serging?

Polyester is the preferred choice for serger threads because of its flexibility and strength. Polyester cone thread in particular is highly valued for its strength, durability and suitability for knit fabrics because of its natural stretch. It won’t snap at high speeds which is important for consistent stitches. Also polyester is resistant to shrinkage and color fading so your projects will look good for a long time.

Another advantage of polyester thread is it comes in a wide range of colors. This allows you to match your thread to your fabric seamlessly and your sewing projects will look great. The thread is also smooth so it minimizes lint build up in your machine.

Nylon Threads for Special Projects

While polyester is the best thread for an overlocker, nylon has its place especially for special projects. Nylon is very strong and stretchy so it’s perfect for sewing stretchy fabrics like spandex or lycra. This elasticity allows the seams to stretch with the fabric without breaking.

But nylon threads are more heat sensitive so be careful when ironing projects made with nylon serger thread. Despite that limitation, nylon is still a useful tool for those working with specific fabrics that require flexibility.

Cotton Threads for Natural Textures

Cotton serger threads are less common but still useful especially for natural fiber fabrics. They have a soft, matte finish that blends well with cotton, linen and other similar fabrics. Not as strong as polyester or nylon, cotton threads are sufficient for lightweight fabrics.

One drawback is that cotton threads produce more lint so you may need to clean your serger more often. But the look of cotton thread is worth the extra maintenance for some projects.

The Magic of Wooly Nylon

Woolly nylon thread is a special type of thread that expands when stretched, gives great coverage and softness. Wooly nylon thread, another variation, is great for creating beautiful stitches on stretchy fabrics like spandex, perfect for swimwear and lingerie. It’s useful for creating decorative edges or hems on knitwear and lingerie. The fluffy texture fills in the gaps so the finish is smooth and professional.

This thread is more expensive than regular polyester or nylon but the benefits may be worth it for specific applications. Wooly nylon is also available in many colors so you have more design freedom.

Thread Weight Matters

Thread weight is important in choosing the right serger thread weight for your projects. Thread weight refers to the thickness of the thread, lower numbers means thicker threads. For most serging tasks 40-50 is the perfect weight, it’s a balance of strength and finesse.

Heavier threads (lower weight number) is for more durable seams and lighter threads (higher weight number) is for delicate fabrics. Choosing the right thread weight will make sure the fabric is not too thick or too thin.

Can I Use Regular Thread in My Serger?

Many newbies ask, “Can I use regular thread in my serger?” Yes you can but it’s not recommended. Regular sewing thread is thicker and can cause tension issues that can lead to uneven stitches and machine damage.

Serger threads are designed to handle the speed and tension of serging, for smoother and more reliable results. If budget is a constraint and you need to use regular thread, use it only in the needle positions and pair it with serger thread in the loopers to minimize the problems.

Other Stitch Options

If you don’t have a serger, you might ask, “Can I use my sewing machine as a serger?” A regular sewing machine can’t replicate the serger completely but some stitches are close. The zigzag stitch is a common alternative, it gives a similar edge finish.

Some machines have an “overlock” stitch option which is closer to a serger. These alternatives can work in a pinch but investing in a serger gives you the best results for professional finish.

Choosing the Right Thread for Your Project

Choosing the right serger thread depends on several factors, the fabric type, the finish you want, the purpose of the project and the best serger thread brands. Understanding serger thread colors and its importance will help you choose the right thread for your fabric and seam visibility. Polyester is an all-rounder, nylon and wooly nylon is for specific needs, cotton is for natural fibers and lightweight projects.

It’s a good idea to keep a small stock of different threads so you have flexibility in your projects. Testing threads on scrap fabric before starting your main project will give you an idea how it will perform and save you time and frustration in the long run.

How to read thread labels and understand thread specs

When buying serger thread, reading the thread label and specs is important to make sure you choose the right thread for your project. Here are the key elements to look for:

Thread Weight: This is the thickness of the thread. Higher thread weight number means thinner thread, which is good for delicate fabrics, lower number means thicker thread good for more durable seams.
Thread Type: This is the material of the thread, polyester, cotton or woolly nylon. Each material has its own properties and best use.
Thread Color: This is the color of the thread. Some threads have a specific color name or number so you can match it with your fabric.
Thread Length: This is the length of the thread on the cone or spool, important for planning the amount of thread you need for your project.
Thread Ply: This is the number of threads twisted together. Higher ply threads are stronger and more durable.

By knowing these specs, you can make a smart choice and choose the right serger thread for you.

How to evaluate serger thread quality: what to look for and how to test

When evaluating serger thread quality:

Smoothness: High quality serger thread should feel smooth to the touch, no thread fibers protruding. Smoothness ensures the thread glides through the serger without snags or breaks.
Strength: The thread should be strong and not break easily. You can test this by pulling a small section of the thread gently to see if it holds up under tension.
Colorfastness: High quality serger thread should not fade or run when exposed to light and washing. To test this, expose a small section of the thread to light and wash it to see if the color fades or runs.
Consistency: The thread should be consistent in thickness and texture. Inconsistent thread will give you uneven stitches and a less professional finish.

To test serger thread, hold a small section of thread between your hands and feel for smoothness and consistency. Pull the thread gently to test its strength and breakage. Expose the thread to light and washing to test its colorfastness. These simple tests will ensure you’re using good quality thread for your sewing projects.

Thread Life and Storage Tips

Storing threads properly will extend the life of your serger threads and keep them color and strength intact. Store threads in a cool dry place, away from direct sunlight. You can use airtight containers to protect from dust and humidity especially for cotton threads that absorb moisture.

Regularly check your threads for signs of wear, fading or fraying so you only use threads in prime condition. Clean your serger often to prevent lint buildup which can affect machine performance and thread quality.

Serging Tips

Using high quality serger threads, including decorative serger thread, will enhance your sewing projects, durability and finish. Decorative threads like metallics and rayon will add visual interest to your serged projects and make them pop. The right thread will not only make your work look good but also extend the life of your garments and crafts.

Try different threads and weights to find what works for you and your style. Whether you’re doing intricate designs or simple hems, knowing your thread options will level up your craft.
