What is an overlock stitch and what is it used for?
To get started, it's essential to understand what an overlock stitch is. Used in both professional sewing and crafts, the overlock stitch allows you to join and overlock fabrics in a single operation. Let's discover why it's become essential for achieving neat fabric finishes .
An overlock stitch is a seam that forms loops around the edge of the fabric . Its main function is twofold: to join two pieces of fabric securely together while preventing fraying . Unlike a classic straight seam, the overlock stitch protects the fabric, gives it greater elasticity, and produces a clean, crisp finish, both inside and outside the garment.
It is particularly used for making stretchy clothing (jersey, lycra) but also for fine or delicate fabrics.
What types of overlock stitches are there?
There are several types of overlock stitches , each with its own unique characteristics and preferred uses. The choice of stitch depends on the fabric being used and the type of sewing desired. We will review the main types to help you make the best choice.
The different types of overlock stitches are distinguished by the number of threads used, their final appearance, and their level of strength. Here are the main variations:
- 3-thread stitch : ideal for overcasting and joining light to medium fabrics.
- 4-thread stitch : perfect for stretchy fabrics, providing a strong assembly with a little elasticity.
- Rolled stitch : fine and decorative finish on very light fabrics such as muslin or organza.
- Flatlock stitch : visible flat seam, ideal for sportswear or decorative effects.
Quick summary :
- 3-thread stitch : simple finish, soft seam
- 4-thread stitch : reinforced finish, stretch seam
- Rolled stitch : light, decorative hems
- Flatlock stitch : decorative, reversible stitching
Which machine should I use to make an overlock stitch?
Choosing the right machine is crucial for achieving a quality overlock stitch . Are you undecided between buying a serger or using a serger sewing machine ? Here's what you need to know.
A serger is designed exclusively for overlock sewing. It typically uses 3 to 5 threads, features a cutter to trim fabric edges, and ensures a professional finish. A conventional sewing machine , on the other hand, can mimic overlock stitching with specific settings and presser feet.
| Criteria | Overlock sewing machine | Dedicated overlocker |
|---|---|---|
| Number of threads | 1 to 2 threads + imitation overlock | 3 to 5 real threads |
| Cutting the fabric | No | Yes (built-in knife) |
| Seam strength | Average | Excellent |
| Ideal for | Beginners, small finishing touches | Professional sewing |
