Best Serger Thread: What To Use Serger Thread & Brands

After Purchase New Serger Sewing machine Now, the next step is to get familiar with how it works, and one of the most important aspects of serger operation is choosing the right serger thread. The thread you use plays a huge role in ensuring your machine runs smoothly and produces professional-quality finishes. Let’s dive into everything you need to know about selecting the perfect thread for your serger projects, including the best thread brands and types to consider.

Do Sergers Use Special Threads?

Yes, serger machines require a specific type of thread to function optimally. Unlike regular sewing thread, serger thread is designed to handle the unique demands of overlock stitching and multi-threaded seams. Here’s what makes serger thread different:

1. Finer Than Regular Thread: Serger thread is thinner to prevent bulky seams. Since sergers use multiple threads simultaneously, finer threads help maintain a clean, lightweight finish.
2. High-Quality Material: Quality is key! Serger thread is designed to minimize lint buildup, which can clog your machine and affect its performance.
3. Cones, Not Spools: Serger thread comes in large cones that hold anywhere from 1,000 to 12,000 yards of thread. This is because sergers use thread much faster than regular sewing machines.
4. Multi-Thread Use: Sergers typically use 3 to 5 threads at once, so the thread must be compatible with multi-thread stitching.
5. Material Options: Serger thread can be made from polyester, nylon, cotton, or a blend of these materials. Each type has its own benefits, depending on your project.

How to Choose the Right Serger Thread

While it’s true that higher-priced threads often mean better quality, price isn’t the only factor to consider. Your choice of thread should depend on your budget, the type of fabric you’re working with, and the specific applications you have in mind. Here’s a quick breakdown:

• Polyester Thread: This is the most popular choice for sergers because it’s strong, durable, and works well on a variety of fabrics. It’s also resistant to shrinking and fading, making it ideal for garment construction and home decor projects.
• Cotton Thread: If you’re working with natural fabrics like cotton or linen, 100% cotton thread is a great option. It’s soft and breathable, but it’s not as strong as polyester.
• Nylon Thread: Known for its strength and elasticity, nylon thread is perfect for stretchy fabrics and heavy-duty projects. However, it’s not recommended for high-heat applications.

Best Serger Thread: What Is the Best Serger Thread? A Comprehensive Guide

When it comes to serger machines, the thread you choose can make or break your sewing experience. With so many serger threads on the market, it’s easy to feel overwhelmed. But not all threads are created equal—some are high-quality, while others can lead to broken threads, skipped stitches, and excessive lint buildup. So, how do you find the best serger thread for your projects? Let’s break it down.

What Makes a High-Quality Serger Thread?

The best serger thread should meet specific criteria to ensure smooth operation and professional results. Here’s what to look for:

1. Minimal Fuzz: High-quality threads have fewer short fibers sticking out, which reduces lint buildup in your machine. Less lint means fewer cleanings and better performance.
2. Consistent Thickness: The thread should be evenly spun without lumps or irregularities. Uneven threads can cause tension issues and breakage, especially at high speeds.
3. Tangle-Free: A good thread should be free of knots and tangles, ensuring smooth feeding through your serger machine.
4. High Breaking Strength: Sergers operate at speeds of around 1,500 stitches per minute, so the thread needs to be strong and durable to withstand the stress.
5. Cost: While higher-priced threads often indicate better quality, they’re worth the investment for reliable performance and longevity.

Types of Serger Thread

The most common type of serger thread is 100% polyester, but not all polyester threads are the same. Here’s a breakdown of the different types:

1. Spun Polyester:
   • Affordable and widely available.
   • Prone to moderate-to-high lint buildup.
   • Less durable compared to other polyester threads.
2. Filament Polyester:
   • Stronger and smoother than spun polyester.
   • Produces less lint, making it ideal for high-speed sergers.
3. Core-Spun Polyester:
   • Features a polyester core wrapped in cotton or another material.
   • Combines strength with heat resistance, making it versatile for various fabrics.
4. 100% Cotton Thread:
   • Perfect for natural fabrics like cotton or linen.
   • Produces more lint but offers a soft, breathable finish.

When to Switch ThreadsIf you’re experiencing stitch quality issues even after adjusting your serger tensions or changing needles, it might be time to switch threads. Different fabrics and projects may require different types of thread. For example:

• Polyester thread works well for stretchy fabrics and heavy-duty projects.
• Cotton thread is ideal for lightweight natural fabrics.
• Core-spun polyester is a great all-rounder for mixed fabrics.

Additionally, if your thread is running low on the cone and starts to look wavy or uneven, it’s best to stop using it on your serger. Consider reserving it for hand-sewing projects instead.

Decorative Threads and Sergers

Did you know you can use decorative threads like metallic thread, rayon thread, lightweight ribbons, and even yarns on your serger? These materials can add a unique touch to your projects, but they require a looper attachment and careful handling.

Best Uses for Woolly Nylon

• Stretch fabrics
• Lingerie and swimwear
• Decorative edges and rolled hems

Embroidery Thread vs. Serger Thread

While embroidery thread is great for decorative stitching, it’s not suitable for sergers. Here’s why:

• Finer and Less Durable: Embroidery thread is thinner and more delicate, making it prone to breaking or tangling in a serger.
• Not Designed for Loopers: Serger thread is specifically engineered to withstand the friction caused by loopers, whereas embroidery thread isn’t.

If you want to use embroidery thread for decorative purposes, limit it to the loopers and pair it with serger thread in the needles for stability.

Best Serger Thread Colors

Choosing the right thread colors for your serger can save you time and effort. Here’s what you need to know:

1. Left Needle Thread: This is the only thread that might show on the right side of your project, so it’s important to match it to your fabric.
2. Looper Threads: Since these threads are mostly hidden, you don’t need to match them exactly. Opt for complementary colors or neutral shades.

Tips for Choosing Thread Colors

• Mix and Match: Use white or beige looper threads for light fabrics and black or gray for dark fabrics.
• Build a Basic Palette: Stock up on white, neutral, and dark shades (like black, navy, or dark gray) for versatility.
• Go Darker: If you can’t find an exact match, choose a darker thread color rather than a lighter one.

For smaller projects where color matching is crucial, consider using all-purpose thread on small spools.
