What is the difference between a coverstitch machine and an overlocker?

Before deciding which one to choose, it is important to understand what a coverstitch machine and overlocker do. These two machines have very distinct roles in the world of sewing, and confusing them can lead to an unsuitable purchase. Here is how they clearly differ.

What is the purpose of an overlocker?

The overlocker is designed to join fabrics while cutting excess material and creating a clean edge finish. It is ideal for stretch fabrics or those that fray easily. Widely used for clothing, it provides a professional and durable result.

It uses 3 to 5 threads and 2 needles to create a serger stitch, very strong, often used for the inner seams of garments. It is fast, efficient, and essential for anyone who wants to sew neatly.

• Layers, cuts, and overlocks in one pass
• Essential for stretch fabrics and jerseys

What is a coverstitch machine for?

The coverstitch machine or coverlock does not join fabrics. Its role is to create professional hems, especially on t-shirts, leggings, or sportswear. It creates a coverstitch visible on the right side and loops on the wrong side.

It works with 2 to 3 needles and 3 to 4 threads, and allows sewing elastic hems without puckering. The coverstitch machine is therefore perfect for edge finishing, but does not replace an overlocker.

• Specialized in flat and elastic hems
• Perfect finish on mesh, jersey, lycra

The main differences to remember

Here is a clear summary of the essential differences between these two machines:

Coverstitch machine and overlocker: are they complementary?

It is often thought that you have to choose between the two, but in reality, they are two machines with very different uses but perfectly complementary, especially in stretch or sportswear sewing.

Common features between the two machines

Even though they do not perform the same task, the overlocker and coverstitch machine share several useful features to know.

• Fast machines designed for professional finishing
• Suitable for stretch or delicate fabrics
• Requires precise threading and appropriate settings

Practical complementarities in sewing

In sewing, the ideal is to have both machines to benefit from a complete workflow: the overlocker allows for neat assembly, while the coverstitch machine finishes the garment with a soft and clean hem.

• The overlocker ensures the strength of internal seams
• The coverstitch machine elegantly finishes visible edges
• Together, they allow for the creation of professional garments from A to Z

Should you invest in a coverstitch machine or a serger?

The choice between coverstitch machine and serger depends on your practice, budget, and the types of fabrics you use. Each machine has its advantages, but they are not interchangeable. Here is how to guide your decision.

For sewing beginners

If you are new to sewing and want to improve your finishes, the serger is the first good investment. It allows you to assemble pieces quickly, with a clean finish. The coverstitch machine can come later, once you master the basics.

• Priority to the serger for its versatility
• Easy to handle after a short learning period

For regular or professional sewists

If you often sew garments in jersey or lycra, having both machines is an undeniable advantage. The coverstitch machine then becomes essential to achieve a perfect and stretchable hem.

• Double investment for a professional result
• Time and quality savings on all finishes

Are there combined machines?

Yes, some brands offer combined machines serger/coverstitch (also called combi or 5-thread). They are convenient but often more complex to adjust and less efficient than two separate machines.
