Although it's known as an advanced model, the Brother 2340CV (appx. $299) doesn't have the hefty price tag that you'll find on industrial machines. You can rely on it for decorative and chain stitching without any unsightly waviness, stretching, or bunching.

Easy to thread, even by novice sewers

Wide variety of cover stitches
- Sewing Land
Color-coded guides, labels, and threaders allow seamless stitching and discards confusion involved in placing threads. It also makes the output neater and more accurate and allows the creation of various decorative thread patterns.
- House Of Meggs
The Brother coverstitch is very user-friendly. Threading is a breeze, especially if you already have a serger and are used to threading it. On the coverstitch, there is only one lower thread to worry about, and it's very easy to thread.

I don’t know how I ever lived without a cover stitch machine.

What experts didn't like
Some users stated that the feeder skipped stitches and went too fast at some points.
- Teach You to Sew
Fabric can be hard to release
- Wiki EZ Vid
The instructions provided aren't very clear.
- Best Advisor
Some people had issues with bunching threads. No free arm capability
- Sewing Land
You need to manually control the tension in the thread. This can be a little taxing for some users. You’ll have to adjust the each thread’s tension separately. You’ll have to press a total of 4 buttons to adjust the tension which is difficult without practice.
- House Of Meggs
Coverstitch machines are not cheap, and on my budget, I had two to choose from: the Brother and the Janome Cover Pro 900cpx. The Janome has a free arm, but the Brother had a triple-stitch function. I vacillated and ultimately chose the Brother. I do regret the decision and wish I had bought the Janome, because I never use the triple stitch, but I often wish I had the free arm.
- The Itenerant Seamstress
The manual tension release has been reported to be complicated for some users. Separate buttons must be pressed for each thread; meaning up to four may have to be pressed at the same time.
- Serger Pro
No free arm. Needs a true serger to cut the fabric
- Best Serger Reviews
I spent more money on this machine than any other sewing machine I have, and unfortunately it’s the wimpiest, most finicky one of the bunch.

An Overview On Sergers

Whether you’re a novice sewer or an expert in your craft, it’s likely you’ve come across a serger. This is a specialized sewing machine which is designed to finish the edges of material. All in one step, a serger encloses the seam inside a casing of thread, providing a neat finished product. You can find sergers that have varying thread options. The number of threads your serger uses will affect the kinds of stitches you’re able to make.

A 2-4 thread serger provides a safety stitch, ideal for woven or knit fabrics. A 3-4 thread serger provides a much wider and stronger seam, plus they may also have a rolled-hem capability. On the other hand, a 5-thread serger offers a number of seam capabilities, including the kinds of seams you see on ready-made clothes. It can do both strong seams and seam finishes.

You may be wondering whether a serger can replace a sewing machine, or vice versa. The truth is that while you can complete projects without one or the other, in many cases both machines are required because they do different jobs. Both sewing machines and sergers are able to gather fabric, hem knits, do narrow rolled hems and piping. However, sergers are not standalone machines that can do important tasks such as buttonholes, zippers, top-stitching and facings, for which you’ll still need a sewing machine.

A serger ensures that the insides of the items you sew are neat and will not unravel. The seams that a serger sews provide a lot of strength, which are ideal for children’s clothing and other items where durability is key.

DWYM Fun Fact

While having a sewing machine is vital for many different kinds of projects, there are some projects that you can actually complete by just using your serger. A fleece blanket is a great beginner project for those who are just getting started on a serger. Fleece is an easy material to work with and is highly forgiving if you make a stitching mistake. You can make fleece blankets in multiple sizes, from crib to king.

Infinity scarves are a fashion trend that’s here to stay. This versatile accessory can be made from sheer or knit fabric, and is a good first project for your serger. If you want to practice your serging skills, also consider making a table runner. This is a great way to add style to your dining table while learning the ins and outs of your new machine.

The Serger Buying Guide

  • The most important element to consider when buying a serger is the amount of experience you have sewing. Typically, sergers are best for intermediate or advanced sewers who are comfortable around a regular sewing machine. If you’re new to sergers and new to sewing, opt for a basic model with the foundational features, which will be enough to complete the type of projects you’re working on.
  • The basic functions you want to ensure your serger has include color-coded threading and adjustable thread tensions. A detailed threading guide makes it easy to get the job done, while adjustable tensioning enables you to create a much smoother line.
  • Also look at the differential feed, which is one of the key features on a serger. This helps to make sure that knits and other stretchy fabrics don’t bunch up or stretch while being serged. You can also use this feature to sew lettuce edges and ruffles with the serger.
  • Take a look at what tools come with the serger, because many of these are necessary for a lot of projects. You may need a heavy-duty knife, tweezers, needles, spreader and screwdrivers.
  • Having a visual instruction booklet or video is key for many shoppers. This way, you can learn exactly how to start using your serger and trouble shoot any issues you come up against.
  • If speed is a factor that’s important, take a look at the stitches per minute metric. Many sergers can sew over 1,000 stitches per minute, helping you complete your projects at a much faster pace.
  • Sergers can be bulky and difficult to move around. If you foresee needing to transport your serger, opt for one that comes with a carrying handle, which makes it much easier to transport your machine.
