Best Serger Thread: Recommended for 2021

Serger threads aren’t something everyone is familiar with, unless you use industrial sewing machines or make a lot of clothes regularly. The best serger threads are large spools of thread, each containing 2000 to 3000 yards of thread. These threads are generally used in the serging process, not in regular sewing or embroidery.

It’s very important to choose both the right serger and the best serger thread for your sewing process. Finer than regular thread, serger threads are used in sewing the edges of fabric so that they don’t fray or bend when using the clothes.

Even if they might seem like a simple tool in sewing, it is very important to choose the right serger thread for your projects.

Factors to Consider While Buying Serger Thread

If you are thinking of buying serger thread for your sewing projects, there are some factors you need to consider.

1. Quantity

Of course, quantity is an important factor because best serger threads mostly come in sets instead of in single pieces. If you work commercially or with a lot of projects, you’re going to need a lot of serger thread spools around you at all times.

Serger thread spools come in sets of 4, 6, 12 and more, depending on the set you want. For large projects, you might end up needing sets that come with 12 or more thread spools, or order multiple sets.

2. Color Options

Serger threads are usually available in basic colors, like white, beige, taupe and black, but also in rainbow colors. Some sets come with basic white colors, i.e. the IZO Home Goods 4-Pack of 6000 Yards and some come in a mixture of black and white, like the RockDaMic 6-Pack of 6000 Yards.

There are some other sets, however, that are more colorful, like the Simthread 63 Colors Polyester Embroidery that comes in 63 colors and the New Brothread 40 Colors Polyester Embroidery Thread that comes in 40 different colors.

If you are using these threads in quilting, embroidery, making tapestries or any other projects that require a lot of different color options, you can find them in the two colorful sets mentioned above. Otherwise, for regular sewing and repairing purposes, the basic colors are usually sufficient.

3. Length

With basic colored serger thread, you get a lot more thread per spool than in the colorful ones. For example, the white colored IZO Home Goods 4-Pack of 6000 Yards has 6000 yards of white thread in each spool, which makes it 24,000 yards of thread in a single set. Compared to the basic colored sets, the colorful ones like Simthread 63 Colors Polyester Embroidery come with 550 yards of thread in each spool.

In fact, the more spools in a set, the less yardage you can get in each spool. This is a standard balance in almost all the sets available in the market.

4. Weight

The standard weight of most serger thread is 40 WT, which you will find mentioned in most sets. Any high-quality serger thread will be 40 WT. polyester thread, because these kinds of threads have a special coating on them.

The coating allows the thread to withstand any amount of tension and pressure, even when used in a fast and heavyweight commercial sewing machine.

5. Material

For serger thread, the most common material is polyester, which makes the thread both strong and durable. 40 weight threads can also be made from rayon, but the ones made from polyester are shinier and can withstand more pressure. Therefore, the best threads for serger spools should ideally be made from high quality polyester.

6. Versatility

With the more colorful sets, you can use the serger threads for embroidery and quilting beside simply sewing and repairing projects. Since most serger threads are made from high quality polyester, they are shiny and bright, and can be easily used as thread for decorative embroidery.

7. Compatibility

Finally, since most of the time, serger thread spools are used with sewing and embroidery machines, they have to be compatible with the machine you already have at home. Most serger threads come in plastic spools that can easily fit the sewing and embroidery machines of most renowned brands.

These are some of the factors that should ideally be considered when you are looking for serger threads for your sewing and embroidery projects.

Can Regular Thread be Used in a Serger?

Ideally, serger thread should be used in serger spools, but sometimes, it is difficult to find the exact color match.

Since serger threads are usually manufactured in some basic colors, it might be hard to find a specific color for overlocking and serging.

Serger threads are generally 2-ply threads whereas regular threads are 4-ply ones. This means that regular threads are double in both width and weight compared to serger thread. Using regular thread on your seams instead of serger thread will make your seams heavier and thicker because of the thread.

Even though regular threads are heavier and thicker, they can be also less reliable than serger thread. Because serger threads are made from high-quality polyester and come with a special coating on them, they can withstand pressure and tension. Regular thread might break when used around the seams but serger threads will not.

This is why, it is highly recommended that only serger threads are used in sergers when overlocking or mending seams, even though, technically, regular thread can be used.

Conclusion

For repairing, sewing, quilting, embroidering, tapestry work or dress making, serger threads are an absolutely necessary tool if you want your projects to last long.
