The first thing to know, especially if you are looking for a serger for beginners, is that a serger is not a sewing machine and cannot replace one.
It has various functions. Used alongside a standard sewing machine, it complements its capabilities and allows you to achieve a professional finish on your projects.

If you are just starting to sew, the first thing to consider is a good sewing machine. SewShop recommends buying a serger later on, to achieve a professional finish.
The overlocker is primarily used for garments. It sews and finishes the edges while trimming the excess fabric.
It works with both lightweight and heavy fabrics. It becomes indispensable for jersey, swimwear Lycra, and all stretch fabrics.
With specialized presser feet, it can gather fabric, attach elastic, beads, and cording, and create rolled hems. There are many serger models available; each offers different stitches and operates using 2, 3, or 4 threads and one or two needles—with some models even supporting 5 threads.

The overlocker operates using two loopers and one or two needles. The loopers carry the threads that form loops on both sides of the fabric, thereby securing the raw edges. These threads interlock with the needle threads to form the overlock stitch.
The number of threads determines how many needles are required. A 3-thread or 2-thread serger uses one needle. A 4-thread serger uses two. Some models also offer a "5-thread safety stitch" finish: two threads form a straight seam—known as a chain stitch—while three finish the fabric edge.
The 5-thread stitch is widely used in the industry for workwear and jeans. A professional overlock machine of this type is needed when you require highly durable seams combined with overedging.

Each thread has a dedicated tension control. This allows you to adjust the thread tension for any fabric and achieve professional results.
Differential feed is now a standard feature on these machines—given that most fabrics are synthetic and stretchy—to prevent puckering and ruffling. On the Pfaff Admire 1000, for example, it operates using two rows of feed dogs. By adjusting the differential feed, you can also create decorative gathers and ruffles.
The same goes for the adjustment of stitch length and cutting width as well as colored tracks for easy threading. The best machines guarantee consistently perfect results on any material.
The threading system is a factor to consider, especially for beginners. The Necchi N183 opens on both sides, revealing the lower looper threading path. SewShop always delivers machines like the Juki MO-50eN and the Pfaff Admire 1000 pre-threaded; the latter features color-coded paths and a safety lock that prevents sewing when the front cover is open.
Color-coded paths assist with threading. Also, check the included accessories: the Pfaff Admire 1000 comes with a waste tray, needles, and a two-thread converter for finishing delicate fabrics.
Some sergers combine standard cutting and sewing with the coverstitch.

A serger with coverstitch capability is ideal for advanced sewing projects or if you want to avoid purchasing two separate machines. It combines in a single product an advanced overlock and a coverstitch machine capable of at least four types of stitch.
There are also machines that perform only 2- and 3-needle cover stitches and the chain stitch.
These are highly specialized models. SewShop recommends them to seamstresses and small workshops looking for a machine that is always ready to produce professional hems on leggings, intimate apparel, polo shirts, and T-shirts.

A sewing machine assembles garments using standard stitches. An overlocker, on the other hand, sews, trims excess fabric, and finishes the edge in a single step. It does not replace the sewing machine but complements it; for this reason, it makes sense to buy one later.
The coverstitch is used for hemming T-shirts, polo shirts, leggings, and knitwear. A combination model is a good choice if you are an advanced sewer or want to avoid buying two separate machines. A dedicated machine, on the other hand, is recommended for seamstresses and small workshops that want a machine ready for immediate use.
