Overlocker sewing machines are used to sew the edges of two pieces of fabric for seaming or hemming. Overlocker machines have many names such as sergers or cover-stitch machines, but the purpose of each of these is slightly different. 

If you’re in the market for the best overlocker, there are many things you’ll want to understand and features you’ll need to look out for. In this review, we’ll break down the best sergers and help you choose the right one for your needs and skill level. 

What is an overlocker or serger? 

Overlockers originated in industrial sewing and remained there for a long time, but in today’s world, they’re small and affordable enough for anyone to buy one for their home. Overlockers are also called sergers, and they’re used to overlock stitches and close edges of material to prevent fraying or damage. 

In some cases, tailors use sergers to trim off sections of the excess seam, so you don’t have to do it later when you’re finished sewing. These machines are excellent for edging and hemming, and they add a more professional look and clean finish to the job. 

Some might say that these machines aren’t necessary because you can do the same job with a regular sewing machine, but there are a few different reasons why this isn’t true. 

Sergers use loopers to feed from as many as seven cones, which makes the stitches more pliable. This component is the essential selling point of sergers because they add more technical elements to the clothes and last longer when performed this way. 

You cannot use an overlocker by itself, and for most projects, you will still need to have a sewing machine. An overlocker or serger is meant to accompany the traditional sewing process. 

What makes an overlocker machine different from a traditional sewing machine

Since these machines are less common, many people might be unsure of what they do. A serger is a form of a sewing machine, but its purpose is different. Here are some of the differences between the two

  • Bobbins – A traditional sewing machine comes with one bobbin, whereas a serger can have up to five. 
  • Threads – Your regular sewing machine has only one thread, but sergers come with as many as three or four.
  • Speed – A traditional sewing machine requires much human intervention and control for it to function. A serger runs automatically, and the machine stabilizes the thread flow. 
  • Purpose – While we find sewing machines and sergers in commercial and home use, sergers are most common in the mass production of clothing. 

Your serger will sew almost twice as fast as a sewing machine, which takes some of the load off the sewing process. 

Types of serger stitches

You can do a lot with the best overlocker, and there are many stitches to add flair and excitement to your project. This factor alone is what turns people’s eyes to the serger even if they’ve never thought about purchasing one before. Here are some of the stitches you can do with a serger: 

  • Three-Thread Overlock – Many use an overlock stitch when creating a blind hem. This stitch is great for delicate fabrics because it doesn’t put a lot of pressure on them, and you still have plenty of control. 
  • Four-Thread Overlock – A four-thread overlock is a correct choice when finishing a seam. This stitch creates a seam that is long-lasting, durable, and strong on clothes that experience a lot of wear and tear. 
  • Two-Thread Rolled Edge – If you need a narrow seam on sensitive material like household fabrics such as tablecloths and curtains, you can add plenty of detail using rolled-edge stitches. 

Who should buy an overlock machine? 

If you’re new to the world of sewing, that’s okay. We understand how all of this might be a little overwhelming when you’re not sure what you’re looking at or reading about. Lucky for you, there are many jobs that a serger is useful for, even if you’re a beginner. 

Sergers are the best choice for finishing a product when hemming, edging, or seaming is needed. The serger reduces the amount of work it takes to create garments, but there is a steep learning curve here. You can’t simply purchase one of these and fire it up right away; it takes some time. 

You can use an overlock machine for some of the following:

  • Knit fabrics
  • Quilting
  • Pajamas
  • Delicates

If you need to sew zippers, buttonholes, or decorative areas, you won’t want to use a serger, and you’ll have to use a traditional sewing machine alone.

Features to look for 

Now that you understand a bit more about what an overlocker can do, it’s time to take a look at some of the specific features you’ll want to have on the one you purchase. If you have experience with these machines, you can likely skip right to the review section because you know all of this already. 

If you’re getting acquainted with sergers, you might want to stick around and take a look at some of the following features: 

Power 

Power is important for all sewing machines because it impacts how efficiently you can work. A powerful serger will grant you the freedom to work on many types of fabric, whether tough, durable, sensitive, or delicate. It’s important to find a middle ground in terms of power and functionality.

Stitch Capacity 

The stitch capacity will vary from machine to machine, but the higher, the better in most cases. Overlockers create firm edges, so they need to offer a combination of many different stitch patterns based on the fabric you’re working on and the desired end result. 

A larger stitch capacity will provide you with more options, which is what you want when you’re spending a decent amount of money. 

Cost

Speaking of money, the cost is important too. The price of your machine will depend on how many features and functions you desire. Take the necessary time to compare different machines and establish a budget that provides you with the features you want but doesn’t drain your bank account. You should be able to get the best overlocker for an affordable price. 

Sewing Speed

When compared to traditional sewing machines, overlockers operate at a much higher speed reaching as high as 1500 stitches per minute. The faster the machine, the quicker you can complete projects.
