better finish.
Choosing your first overlocker should feel exciting. Here is how to match the Janome ML544D, Huskylock S15, Brother 2504D or Singer 14HD854 to the sewing you want to do.
Compare the four machines ↓Turn a handmade garment inside out. Those neatly wrapped seam edges are often the work of an overlocker. It is the machine that helps jersey seams move with you, keeps fraying woven edges tidy and makes a row of unfinished garments feel much closer to finished.
The first purchase can be confusing. There are loopers instead of a bobbin, several thread cones and a knife beside the needle. The reassuring part is that the core skills are learnable—and you do not need the longest feature list to make clothes you are proud of.
Which first overlocker should you choose? Start with a machine that offers four-thread overlocking, differential feed and a threading route you feel comfortable learning. The Janome ML544D stands out for its included bonus attachments; the Brother 2504D for F.A.S.T. lower-looper access; the Huskylock S15 for two-, three- and four-thread versatility; and the Singer Heavy Duty 14HD854 for that same thread flexibility with an emphasis on its cutting system and metal frame.
What does an overlocker actually do?
An overlocker, also called a serger, wraps thread around a fabric edge. With the appropriate stitch selected, it can join a seam, trim the excess fabric and finish the edge in one pass.
For a cotton T-shirt, a suitable four-thread overlock can construct a flexible seam. For woven trousers, you might sew the main seam on your sewing machine and overlock the allowances to control fraying. For a lightweight scarf, a rolled hem creates a compact decorative edge.
Your sewing machine still has an essential role: zips, buttonholes, ordinary straight stitching and topstitching. If you are buying your very first sewing machine of any kind, start there. An overlocker is usually the next useful addition for someone who wants to sew more garments.
For construction
Two needles and two loopers. A practical starting point for many knit garment seams, with the setup tested for the fabric and pattern.
For edge finishing
One needle and two loopers. Useful for neatening seam allowances, rolled hems and selected decorative techniques.
For a lighter finish
A needle and looper with the appropriate converter. Useful for selected fine edges and decorative work. Available on the S15 and 14HD854.
Thread count describes the stitch setup, not a quality ranking. A good three- and four-thread overlocker can cover a great deal of everyday dressmaking. Two-thread capability is worth choosing when its lighter finishes are something you expect to use.
What about the twin lines on a T-shirt hem? Those are commonly made with a coverstitch machine. None of these four overlockers produces a true coverstitch. You can begin with a suitable stretch or twin-needle hem on your sewing machine and consider a coverstitch later. Our overlocker versus coverstitch guide explains the difference.
Janome ML544D vs Huskylock S15 vs Brother 2504D vs Singer 14HD854
All four offer the essentials for everyday garment overlocking. The more meaningful differences are threading access, two-thread capability, the sewing surface and what comes in the box.

Four good starting points.
Choose the one that fits you.
For garment sewing and room to explore
Janome MyLock ML544D
The Janome ML544D—sometimes shortened to “ML544”—is a three- and four-thread overlocker with colour-coded thread paths, lay-in tensions and a quick rolled-hem changeover. Raise the presser foot to release the tension discs when threading, as directed in its instructions.
Its package is a useful reason to look closely: a blind-stitch foot, gathering attachment, elastic gathering attachment and cording foot give you techniques to explore after the basic seam becomes familiar.
Imagine starting with a jersey top, then trying a gathered skirt detail or guided cording on another project. Those extras can be useful without requiring you to buy every attachment separately.
Know before choosing: this model has a flatbed rather than a free arm and does not offer two-thread stitching. Small circular openings can still be sewn in the round with suitable handling; try a sample to see what feels comfortable.

For more choice in lighter finishes
Husqvarna Viking Huskylock S15
The Huskylock S15 offers two-, three- and four-thread sewing, a free arm and 15 advertised stitch options. Its appeal is the range of finishes you can grow into, from garment construction to fine edges and decorative flatlock effects.
Choose it if your project list includes both jersey garments and lightweight scarves, frills or other pieces where a less bulky finish could be useful. Two-thread sewing uses its converter and the appropriate setup; it is an extra technique to learn when you are ready.
The free arm and waste tray are practical touches. As with any domestic free arm, an opening still needs to fit around it—very small cuffs may be easier to work another way.
Know before choosing: the colour-coded paths guide manual threading. The machine does not automatically choose tensions for each fabric. Learn its basic four-thread seam first, then add other finishes gradually.

For an approachable threading routine
Brother 2504D
The Brother 2504D is a particularly useful model to consider if reaching the lower looper is your biggest concern. Its F.A.S.T. lower-looper system uses a blue lever to move the looper into a more accessible threading position.
That helps with one of the fiddlier parts of conventional overlocking. You still follow the colour-coded route and thread the needles yourself, but improved access can make practice feel more manageable.
Three- and four-thread stitches, differential feed, rolled hemming and a free arm cover a wide range of everyday garment work. The included blind-stitch foot and trim trap add practical value to the standard package.
Know before choosing: “easy threading” does not mean air threading or automatic needle threading. There is no two-thread option. For many first-time garment makers, the three- and four-thread stitches are the ones they will reach for most often anyway.

For varied fabrics and a capable cutting setup
Singer Heavy Duty 14HD854
The Singer 14HD854, often called the “Singer 14HD”, combines two-, three- and four-thread stitching with a metal interior frame, differential feed and a free arm.
Singer highlights its larger cutting knife as a distinguishing feature. That makes it worth comparing if your sewing includes sweatshirt fleece, medium-weight home projects and seam finishing on suitable denim, alongside lighter garments.
It also makes rolled hems and selected flatlock finishes. “Heavy Duty” does not restrict it to thick fabric: the correct needle, thread, tension and feed settings still matter on lighter material.
Know before choosing: a larger knife is not a promise of unlimited thickness. Test dense seam crossings and multiple layers. This is a domestic overlocker, so leather bags, upholstery production and very heavy construction need a separate conversation about appropriate equipment.
Explore the Singer 14HD854 →A stitch-count comparison can mislead. Brands group and count overlock configurations differently. The S15’s advertised 15 options and Singer’s six stitch types are not directly comparable scores. Check the actual finishes you want: four-thread construction, three-thread edges, rolled hems, flatlock effects and, if needed, two-thread work.
Is an overlocker difficult to thread?
It is different from threading a sewing machine. Four routes look complicated at first, but each route has a specific job. The useful question is whether you can see and reach those guides comfortably.
All four machines here use conventional threading. Colour coding helps you follow a path, while features such as Brother’s lower-looper access help you reach it. Neither removes the need to follow the manual’s order.
-
Set up where you can see clearly.
Switch off as instructed before threading. Extend the thread stand fully, organise the cones and open the relevant covers. Use the supplied tweezers and the correct spool supports or caps.
-
Follow one complete route at a time.
Use your model’s exact sequence and presser-foot position. Loopers and needles interact, so a thread that looks nearly correct can still miss an essential guide. Do not substitute instructions for another machine.
-
Practise with four contrasting colours.
Suitable threads in different colours help you identify which thread is forming each part of the stitch. Once you understand the seam, change to colours appropriate for the garment.
-
Keep a successful sample.
Label an offcut with the needle, stitch setup, tensions and feed setting. It gives you a useful starting point next time you sew a similar fabric.
Brother provides a step-by-step 2504D threading video. For any model, keep its own instructions beside the machine and ask for help with the stage that is causing trouble.
If conventional threading is a serious barrier because of vision, dexterity or personal preference, include an air-threading model in your wider comparison. Our air-threading overlocker guide explains what that upgrade changes.
Differential feed: the secret to a flatter seam
An overlocker has feeding sections in front of and behind the needle. Differential feed changes how much fabric the front section delivers relative to the rear. It helps manage fabric that wants to stretch or pucker.
At 1.0
The feed sections move fabric at the same rate. This is a useful starting point for many stable fabrics, subject to the manual’s recommended setup.
Try above 1.0
The front feed supplies more fabric. A higher setting can help prevent unwanted stretching; pushed further, it can gather suitable fabric.
Try below 1.0
The front feed supplies less fabric relative to the rear. This can help with some fine-fabric puckering or create a stretched decorative edge.
Make small changes and check the result on the actual material. Differential feed works alongside presser-foot pressure, thread tension, stitch length and your handling. Support the fabric and let the machine feed it; pulling from behind can stretch the seam you are trying to flatten.
Every machine in this comparison has differential feed. That shared feature matters more to everyday knit sewing than a headline top-speed figure.
Which first overlocker suits your sewing?
Use your likely projects to build a shortlist, then compare the controls and current package.
| Your priority | Where to start | Why |
|---|---|---|
| First T-shirts and everyday knits | ML544D or 2504D | Both cover the core three- and four-thread work. Compare Janome’s attachments with Brother’s threading access. |
| Fine edges and decorative finishing | S15 or 14HD854 | Two-thread capability adds options for selected lighter finishes. |
| Threading access is the main concern | 2504D | Try the F.A.S.T. lower-looper position and decide whether the route feels comfortable. |
| Gathering, elastic and cording techniques | ML544D | Its bonus attachments are a useful package advantage if those techniques interest you. |
| Fleece and medium-weight home sewing | Compare 14HD854 with your alternatives | Assess the cutting system on a representative sample, especially the bulkiest seam crossing. |
| Cuffs and sewing in the round | S15, 2504D or 14HD854 | Each has a free arm. Check whether your actual opening fits; a flatbed technique may suit very small openings better. |
| Parallel coverstitched T-shirt hems | A coverstitch machine | That finish needs a different stitch system from these four overlockers. |
Our buying advice: shortlist two machines for the work you plan to do most. Compare the threading route, pedal response, access to controls and ease of changing to a rolled hem. Contact Direct Sewing about demonstration availability and bring a sample of the fabric you actually want to sew.
A useful sample includes a plain seam, a curve and a folded seam crossing. Those reveal more about how you will use a machine than a long, straight demonstration on an easy fabric.
Your first overlocker setup
Begin with suitable overlocking thread, needles specified for your exact model, small snips and a few generous offcuts. Four-thread stitching needs four separate thread supplies; matching giant cones are not essential for the very first practice session.
Browse overlocker thread at Direct Sewing and use our Coats Astra, Madeira Aerolock and Toldi-Lock comparison to understand the options. Start with an appropriate everyday thread before experimenting with decorative or textured looper threads.
Check the needle system before buying spares. These models do not all have identical needle requirements. Match the system, point and size to the machine’s manual and the fabric. A packet labelled “overlocker needles” is not automatically suitable for every overlocker.
A sensible first project
Start by finishing the raw edges of a stable woven offcut, then practise a four-thread seam on a forgiving knit. Follow with a simple garment pattern that explains its overlocker steps. Respect the pattern’s seam allowance: the knife trims fabric away, so check the cutting line before sewing.
Remove pins and clips before they reach the presser foot and knife. Secure thread-chain ends using the method recommended for the seam, and clean away lint regularly with the machine switched off. Follow the manual for oiling and other maintenance.
For help beyond your first project, Direct Sewing’s machine servicing team is based in Henderson, Auckland. You can also contact the team to discuss machines, supplies and the finish you want to achieve.
First overlocker FAQs
What is the best overlocker for a beginner in NZ?
The best match depends on the projects and threading system you prefer. Compare the Janome ML544D for its included attachments, Brother 2504D for lower-looper access, Huskylock S15 for versatile two-, three- and four-thread finishes, and Singer 14HD854 for its cutting-focused design.
Is an overlocker the same as a serger?
Yes. In this guide, both names refer to a machine that wraps thread around the fabric edge and can trim and join suitable seams in the same operation. “Overlocker” is the more familiar term in New Zealand.
Should I buy a sewing machine or an overlocker first?
For general sewing, start with a sewing machine. It handles tasks such as straight seams, zips, buttonholes and topstitching. Add an overlocker when you want faster edge finishing and flexible seams for garment sewing.
Do beginners need a two-thread overlocker?
Usually not for basic garment construction and raw-edge finishing. Three- and four-thread stitches cover many everyday tasks. Two-thread sewing is useful when selected lightweight or decorative finishes are part of your plans.
Which of these overlockers has air threading?
None. The ML544D, S15, 2504D and 14HD854 all use conventional threading. Brother’s F.A.S.T. system improves access to the lower looper; it does not use air to thread it.
What is the difference between the Janome ML544D and Brother 2504D?
Both offer three- and four-thread overlocking, differential feed and rolled hems. The Janome includes four bonus feet or attachments and has a flatbed. The Brother offers F.A.S.T. lower-looper access, a free arm, blind-stitch foot and trim trap.
How do the Huskylock S15 and Singer 14HD854 compare?
Both offer two-, three- and four-thread sewing, differential feed, rolled hems and a free arm. The S15 highlights its range of stitch configurations; Singer highlights its enlarged cutting knife and metal frame. Compare handling and the actual finishes you need.
Can all four sew stretch fabric?
Yes, with suitable fabric, needles, thread and stitch settings. Four-thread overlocking is commonly used for knit garment seams. Adjust differential feed to help manage stretching and test that the finished seam has enough give for the project.
Can the Singer Heavy Duty 14HD854 sew delicate fabrics?
It can finish suitable lighter fabrics as well as heavier ones. Its two-thread and rolled-edge options can be useful, but the result depends on the fabric and setup. Test a sample instead of choosing settings from the Heavy Duty name alone.
Can these overlockers make a T-shirt from start to finish?
They can handle many construction seams. Hems, topstitching and some details may still need a sewing machine or coverstitch machine. Follow the pattern’s instructions; none of these four makes a true coverstitch hem.
Does my overlocker have to be the same brand as my sewing machine?
No. They work independently. Choose the overlocker for its controls, threading, stitch options and support. However, needles and accessories must be compatible with the individual machine.
