A good thread is good for about five years. However, it might be challenging to know how long it has been in the store. To check if it’s fit for your project, do a stress test.

Always have your thread where you can see it. Arrange the threads based on colors so you can grab the one you want quickly. Get a thread rack, which generally has rows of spool holders. Racks make it easy to access threads.

Another option is the thread boxes. These boxes are designed with lids to cover the thread. The small compartments of spool holders keep your serger threads separated.

5 Great Serger Threads - Your Finishing Touch for Perfect Sewing Projects

The size of a serger thread is a crucial consideration for any serging project. Thickness influences several aspects of the embroidery design, quilt, and art of clothing. More so, it enhances the tensile strength and tenacity. ThreadNanny Sewing Quilting Serger Threads is 40s/2 thick. This means it’s strong and cannot break easily.


The fabric used determines the durability and strength of a thread. There are different materials used such as;

  • Polyester: This is a synthetic-based material that is purely human-made. It’s durable, low maintenance, and relatively inexpensive. It can withstand moderate heat and can easily be engineered to resemble silk, cotton, or even nylon. However, it’s more abrasive than silk or cotton, and you wouldn’t want to try it out on your expensive silk chiffon.
  • Nylon: It’s a synthetic thread that’s relatively easy to use and inexpensive. A wooly nylon serger thread has good elasticity. Nylon thread doesn’t shrink. Bonded nylon is suitable for utility projects like camping equipment, tool belts, and sports gear.
  • Silk: Silk is flexible, fine, and durable. It holds dye well, lint-free, washable, and available in different weights. Since it’s an animal-based fiber, it works perfectly with booth wool and silk fabric. Often, silk is used in fine embroidery, exquisite tailoring, and sewing buttons.
  • Wool: Wool is an animal-based fiber created from sheep fleece. Wool threads are commonly used in machine or hand needlework.

These are some of the primary materials used in serger threads. Polyester is commonly used since it’s readily available and inexpensive.


Serger threads cone in cones or spools. When using spools, it’s advisable to use the vertical pin fitted on top of your machine. Placing the thread horizontally might cause tension. Spools are wound with a straight wind.

Cone shape, such as AK Trading All Purpose Sewing Thread, is generally cheaper than spool thread. The wider end faces down while the narrow end faces up. This allows the thread to be pulled easily. And due to its inexpensiveness, most people find it appealing.


The purpose of buying the best serger thread is to ensure it will last for long. Several factors determine the durability. For instance, the cord of the thread is an essential factor to pay attention to. Corded threads can be described as 2, 3, and even 9-ply threads. A corded thread is thicker and stronger, hence durable.

The material used also plays a vital role. Polyester is a synthetic fabric designed to be durable. Therefore, when buying a serger thread, choose a corded one and one made from durable material. This way, your stitches on the garment will last long.

Color variation

5 Great Serger Threads - Your Finishing Touch for Perfect Sewing Projects

Serger threads are available in different color variations. ilauke Overlock Sewing Thread is available in several colors to choose from. For the right color, unravel the end of the thread and place it across the fabric. The right thread will disappear or blend well with the material. For a multicolored fabric, pick a dominant color of thread. However, having a myriad of polyester and cotton threads in black and white is always a noble idea. Get a uniformly dyed thread which will provide immunity and uniformity when exposed to washing.


Good tensile strength of the serger will hold the stitched seam and hem securely during wear and tear. The absence of faults and smooth surfaces ensures there is less friction between the fabric and needle during high-speed serging.

Ensure the thread is well lubricated to boost its sewability. More so, the smoothness will prevent abrasion. A smooth thread moves swiftly and quickly through the needle and material.



Today, the market is saturated with threads from different manufactures. All brands promise to deliver quality, durable and strong products. However, not all brands are as advertised. Some are more into quantity rather than quality. And if you happen to buy threads from such companies, you’ll get disappointed.

When you’re buying serger thread, get it from a reputable manufacturer. First, check the experience. Vast experience in the field means that the company knows how to engineer high-quality threads. Also, check the technology they use. The spinning and twisting technology will determine the durability of the serger thread.

If you’re new to serging, you may seek advice from professionals in the field. When shopping online, read reviews to get detailed information from previous clients.

Over time, you’ll need to replace your thread. And if you don’t choose a reliable and internationally known manufacturer, you’ll have a hard time getting the right piece. And be vigilant for brands that offer low-ball prices. Cheap can be expensive at the end.


A serger thread that is manufactured today will last longer than a thread that was manufactured 10 or 15 years ago. The material used will also affect the durability of any given thread. However, a high-quality serger thread that is produced today can be fine to be used even in 20 years to come. Thanks to the twisting, spinning, and dyeing technology used today in engineering threads.

Yes, you can. However, using the standard thread on a serger can be quite expensive. You’ll run out in about 15 minutes. Not unless it’s in emergencies, it will be unnecessary to use a regular thread on a serger.
