In my search to find the best overlocker, I reviewed and compared 40+ overlock machines sold in the UK.
This meant weeks of talking to overlocker specialists, analysing online manuals, and scrutinizing sales pages.
I received advice from 12 industry experts: 3 overlocker technicians and 9 overlocker sellers. Here’s what I’ve learned.
Best overlockers:
In my opinion, the best all-round overlocker is the Brother 4234d (Amazon link).
It offers 2, 3, and 4 thread stitches, good build quality, and a very user-friendly threading system (with a built-in needle threader!). I recommend this for people who sew a lot and want a better-built machine. Expect to pay just under £400.
The best budget-friendly option is the Brother 3034dwt (Amazon link).
It has the same excellent threading system as the more expensive Brother (minus the needle threader). It also has more accessories than I’ve ever seen with an overlocker (worth £126!). Like all budget overlockers, it can only sew 3 and 4 thread stitches, but that’s all most people need anyway. Expect to pay around £300.
If you want an overlocker that will thread itself at the push of a button, or choose tension settings for you, I have 3 premium picks below.
**January 2021 update:
Many overlocker sellers are struggling to keep machines in stock.
My alternative for the best all-round overlocker is the Elna 664 PRO (Amazon).
It’s a similar quality and price as the Brother. It also has a great “information panel” on the front which suggests settings for 12 different stitches. This is super helpful and rare to find. It will save you from constantly looking up the settings in your manual.
And my in-stock budget alternative is the Brother 2104D (Amazon). It’s almost identical to the 3034dwt, but it’s missing 2 accessories: the extension table and waste bin. It’s about £200-ish.
I talk more about these alternatives below.

The best all-round overlocker: Brother 4234d
Typically £400-ish. Check Amazon’s price.
Ideal for: Frequent sewists who want lots of features and better build quality.
It creates professional-looking stitches, including the overlock, rolled hem, narrow hem, mock flatlock, and blind hem stitches (stitch photos here). The results look identical to more expensive machines.
It can create more stitches than cheaper 3/4 thread overlockers, thanks to its 2 thread stitch ability. This can’t be added later.
It’s better-built; an overlocker seller said it’s a “good, solid, quite robust option”.
It has one of the best manual threading systems I’ve seen (so important!).
And it’s packed with features that surprisingly many overlockers are missing: a free arm, a built-in needle threader, a waste tray, and free blind hem foot.
I have owned this model personally since 2018. It’s sturdy and simple to use (for a manually threaded machine).
If it’s unavailable, here are my favourite alternatives (in order of preference):
- Elna 664 Pro (Amazon)
- Janome 6234xl (Amazon)
- Bernette Funlock 44 (Amazon)
Scroll down for my in-depth review of these overlockers.
The best budget overlocker: Brother 3034dwt
Typically £300-ish. Check Amazon’s price.
Ideal for: people who just want a cheap overlocker for occasional sewing.
It has the same excellent threading system as the more expensive Brother machine.
It comes with an impressive number of free accessories:
- Free extension table (about £22 if bought separately).
- 3 extra feet (about £80 if bought separately).
- Free waste tray (about £24 if bought separately).
That’s a saving of £126!
Like all budget overlockers, it can’t do 2 thread stitches. You can only make 3 or 4 thread stitches, but that’s all most people need anyway.
You’ll be able to sew the overlock, rolled hem, narrow hem, mock flatlock, and blind hem stitches (photos here).
Be aware that this is a budget machine. It will be made with weaker metals, weaker motors, and more “relaxed” quality control during manufacturing. This is inevitable for any cheap, mass manufactured overlocker.
If you just sew every now and then, it’s good enough to get the job done.
If it’s unavailable, here are my favourite alternatives (in order of preference):
- Brother 2104D (Amazon)
- Brother M343D (Amazon)
- Elna 664 (Amazon)
Scroll down for my review of these overlockers.
The best overlocker with air threading: Juki MO-2000 QVP
Typically £1095.
Ideal for: people who want an easy overlocker that threads itself.
The Juki MO-2000 QVP is one of the best overlockers with air threading and a needle threader. This means it will thread everything for you, so you can start sewing much faster.
An overlocker seller praised Juki’s quality. He said the brand has a long history of making industrial machines.
It also has an information screen that suggests settings for different stitches. This is very unique. It will save you from memorising settings or looking through your manual.
If it’s unavailable, here are my favourite alternatives (in order of preference):
- Husqvarna Amber Air S 400
- Pfaff Admire Air 5000
- Janome AirThread 2000D Professional (Amazon)
- Juki MO-1000 (Amazon)
- Babylock Enspire (Amazon)
Go to page 2 for my review of these overlockers.
The best overlocker with automatic tension: Pfaff Hobbylock 2.5
Typically £649.
Ideal for: people who want perfect stitches without fussing with settings.
If you need automatic tension, the Pfaff Hobbylock 2.5 is your best option.
It will automatically choose tension settings for you, creating (near enough) perfect stitches immediately. You won’t need to experiment with the settings to get a good stitch. This removes a huge frustration.
A technician I spoke to said Pfaff makes nice machines, so you can expect excellent build quality.
Don’t forget that this is still a manually threaded machine. There’s no air threading.
If it’s unavailable, here’s my favourite alternative:
- Success Lucie (typically £399)
Go to page 3 for my review of these overlockers.
Best overlocker with air threading and automatic tension: Babylock Victory
Typically £1000-ish. Check Amazon’s price.
Ideal for: people who want the easiest overlocker.
If you want air threading, a needle threader, and automatic tension, the Babylock Victory is for you. It threads everything for you, and it chooses the right stitch settings automatically.
For a premium overlocker, it’s a decent price too. You could easily pay more for this combination of features.
Babylock has an excellent reputation among industry specialists. 2 overlocker sellers described them as the “rolls royce” of overlockers. You can expect excellent build quality from this machine.
If it’s unavailable, here are my favourite alternatives (in order of preference):
- Babylock Enlighten (Amazon)
- Babylock Acclaim (Amazon)

More overlocker info for beginners:
Here’s how overlockers are different to normal sewing machines.
If you’re not sure what stitches an overlocker makes, or when you would actually use certain ones, check out my beginners guide to overlock stitches. There are lots of close-up photos.
If you’re not sure what features to look for in an overlocker, here are 21 things to consider. I also explain common overlocker terms (like “differential feed”) with lots of photos and videos for visual learners.
I also asked industry experts what makes an overlocker good or bad quality? This is a really eye-opening read. Learn what sacrifices manufacturers make for cheap overlockers.
Needles:
The Brother and Juki machines use 130/705H needles (size 80/12 for lighter fabrics and 90/14 for thicker ones). These are standard needles that will work in your sewing machine too.
Babylock, Janome, Elna, and Husqvarna machines require HAx1SP needles (sizes 75/11 and 90/14). These are standard ballpoint needles that will also work in your sewing machine.
Pfaff, Bernette, and Success machines require ELx705 overlock needles (sizes 90/14 and 80/12).
Overlocker thread:
Overlocker thread is different to normal sewing machine thread.
The thread spools are much bigger and more cost-effective.
The thread is generally weaker. Overlock stitches use multiple threads to create a seam, so each individual thread doesn’t need to be as strong.
I use and recommend the Toldi-lock polyester threads by Gutermann.
Remember that overlockers take 4 threads, so get a set of 4 in black, white, and/or grey and beige (to blend better with coloured fabric).
A size 2500m fits nicely on the machine and will last for ages.
Learn how to use an overlocker
Overlocker manuals aren’t the best at explaining things. I really struggled with the black and white illustrations in mine.
Here are better resources on how to thread an overlocker and sew real projects with it.
Cheap online overlocker classes
If you learn best by seeing, here are the best online overlocker courses I’ve watched.
Creative Bug also has some practical online classes. Here are some great overlocker projects to start with: a 1 hour long-sleeve top, a short sleeve t-shirt, and a tank top.
Will these overlockers work for thick fabric, stretchy fabric, or everyday use?
Will these overlockers sew thick fabric?
All domestic overlockers will sew thick fabrics, like denim and wool.
They’re designed to sew 3 or 4 layers of fabric, and no more than that. Multiple industry specialists told me this.
So going over 4 layers of denim at the seams ocassionally is fine. But you wouldn’t want to do it often.
Domestic machines aren’t designed for intense use. You’ll wear the machine out.
This includes overlockers with “heavy duty” names *cough* Singer *cough*. Don’t let the marketing fool you. All domestic overlockers have limited power and durability.
If you’re going to sew thick fabrics daily, you probably need an industrial machine.
High presser foot lift
If you sew with lofty fabrics, like wool or batting, look for a high presser foot lift.
5-6mm is nice, but even 4mm will fit a lot underneath. My overlocker (Amazon link) can fit 8 layers of denim underneath the presser foot at 4mm.
I haven’t seen any overlocker go below 4mm, so any modern machine you pick will be fine.
If you want extra room, go for something higher. The maximum I have seen is 8mm on premium overlockers.
Will these overlockers sew stretchy fabric?
The most important feature you need for sewing stretchy fabrics, like lycra and swimwear, is “differential feed”.
This stops the machine stretching out your fabric and creating weird wavy seams. It will also stop the fabric becoming puckered.
All modern overlockers have this feature.
Just watch out if you’re buying an old, second hand machine. Triple check that it has differential feed.
Will these overlockers work for everyday use?
Avoid budget overlockers
Using your overlocker everyday will put it under pressure.
Domestic overlockers aren’t designed for intense use, but intermediate and premium overlockers will handle it better.
They’re built with stronger metals, fewer plastic components, stronger motors, and better manufacturing.
No domestic overlocker can compete with industrial machines, however.
A technician told me that better-built domestic machines cost £300 and up.
However, this conversation was pre-pandemic. Overlocker prices have been artificially inflated recently, so this figure is more like £400+ now.
I would not buy anything under this price.
Budget machines involve lots of manufacturing and design compromises, which I discuss more in a separate post.
Clean and oil your machine often
Be aware that you’ll need to clean and oil your overlocker often to protect it. Don’t forget to clean lint from under the needle plate.
One salesperson mentioned an overlocker whose feed dogs broke after just 6 months! The owner was sewing a lot with towel/face wipe materials. She wasn’t cleaning her overlocker enough, especially under the needle plate. There was so much lint under there that the feed dogs broke under the pressure.
A technician told me about a customer who caused £300’s worth of damage to their overlocker. It was because they hadn’t oiled it in certain areas for a long time.
So if you want your machine to cope with everyday usage, make sure you’re cleaning and oiling it often to avoid these problems.
Get your overlocker serviced often
Getting your overlocker serviced every 6-12 months is essential if you sew everyday.
The technician will take the machine apart to clean and oil areas you can’t reach.
They can spot and fix issues early on before they turn into major problems.
Which overlocker creates the most “perfect” stitches?
I’ve looked at stitches made using the cheapest overlockers to the most expensive. They all look the same.
The key to getting good stitches is actually getting the settings right. If you buy a manual machine, this will take experimentation and practice.
If you want perfect stitches without fussing with settings, look for premium overlockers with automatic tension. My favourite is the Pfaff Hobbylock 2.5 (£649).
These premium machines remove a huge frustration, but they come with a big price tag too.
Which overlocker is best for beginners?
If you’ve never used an overlocker before, and your budget is under £400, Brother overlockers are a great option.
My favourites are the Brother 4234d and 3034dwt (Amazon links).
Few budget or intermediate overlockers can compete with their simple threading system.
If you want even better ease-of-use, check out premium overlockers with air threading or automatic tension. These machines make the overlocking process much easier, but they come with a big price tag too.
In-depth review: Brother 4234d (best all-round)
Typically £400-ish. Check Amazon’s price
Ideal for: Frequent sewists who want lots of features and better build quality.
This overlocker is ideal if you want more stitch options, excellent threading, and more durability, all at a (relatively) affordable price.
More stitches
It can do 2, 3 and 4 thread stitches, giving you more stitch options than a 3/4 thread overlocker.
This will let you create the 2 thread overlock, 2 thread rolled hem, and 2 thread mock flatlock (photos here). These are lightweight stitches for finishing lightweight fabrics. If you want to experiment, this is a must-have. You can’t add 2 thread stitches later, so now is the time to consider it.
You can use the rolled hem, narrow hem, and blind hem stitches to hem garments. The first 2 are good for lightweight fabrics. The blind hem stitch can be used on more fabric types, but like all overlockers, it will create a bulkier stitch than a sewing machine’s blind hem. This is because it uses more threads.
The cutting blade is retractable if you want to stitch without cutting.
PS. like all overlockers, it can’t do cover stitches. Only coverstitch machines, and coverstitch-overlocker combination machines can do this. And like all overlockers, it can’t do straight stitches. It’s very different to a normal sewing machine.
Good build quality
Industry specialists told me the 4234d is built well. This is important for regular sewists who need something more durable.
One seller said it’s a “good, solid, quite robust option”.
The best manual threading system (seriously)
I love the colour-coded threading diagrams and stitch illustrations printed on the machine. You won’t need your manual every time you thread it.
The lower looper threading system, which can be horrible in other machines, is excellent. A switch pulls out the hidden lower looper so you can thread it in plain sight. This makes such a difference.
I timed how long it took 2 people on Youtube to thread the lower loopers of the Brother 4234d and the outdated Janome 8002d. (The videos are by Ken’s Sewing Center and Syakademiet).
It took about 3 minutes and 10 seconds to thread the lower looper on the Janome. It was very fiddly. It took about 40 seconds on the Brother 4234d! What a difference.
It also has a built-in needle threader for faster threading; most overlockers at this price don’t. If you struggle to thread the eye of a needle (unsteady hands or bad eyesight?), a needle threader is a must-have.
Extra accessories
A free arm, waste tray, and blind stitch foot are included, which many overlockers are missing.
I also like that the Brother 4234d works with normal sewing machine needles (130/705H in sizes 80/12 and 90/14). It’s a nice cost-saver in the long run. Some overlockers require special overlock needles, like Bernette and Pfaff.
Brother has designed a huge extension table for this overlocker. It doubles as storage for your threads, extra feet, and spare parts. It’s not included. Expect to pay about £80 to buy it separately. I don’t think it’s necessary, however.
Manufacturer’s warranty
Brother offers a 3 year manufacturers warranty, starting from the date of purchase. If your machine develops a fault, not caused by external influences, they will repair or replace it.
If you’re using your machine for commercial purposes, the warranty is for 1 year.
Limitations
I have owned this machine since 2018.
The built-in needle threader works most of the time, but on occasion it fails and I have to retry it 2 or 3 times. I don’t think this is a deal breaker, however.
It’s also quite loud, but that’s normal unfortunately. I’m not aware of any overlocker that’s silent. I did ask an overlocker seller if she knew of any really quiet overlockers, but she didn’t.
If the Brother 4234d is unavailable:
Luckily there are lots of well-designed intermediate overlockers. Here are the ones I researched and liked. They’re in order, starting with my favourite:
- Elna 664 Pro (Amazon)
- Janome 6234xl (Amazon)
- Bernette Funlock 44 (Amazon)
1. Elna 664 Pro
Typically £450-ish. Check Amazon’s price.
It can do 2, 3 and 4 thread stitches.
It has a great “information panel” on the front. This suggests settings for 12 different stitches. This is super helpful and rare to find. It will save you from constantly looking up the settings in your manual.
The threading system is good, and I like the threading diagrams printed on the machine.
It has a free arm, waste bin, and 2 features I don’t see often at this price: tiltable needles, and a built-in “2 thread converter”. These are small conveniences that make replacing the needles and switching to 2 thread stitches easier.
It uses standard sewing machine needles: the ballpoint HA-1SP needles (sizes 11 and 14).
It comes with a separate needle threading device; it’s not built-in like the Brother.
There are no extra feet.
If I couldn’t buy the Brother 4234d, this would be my next choice.
2. Janome 6234xl
Typically £480-ish. Check Amazon’s price
When I asked overlocker specialists which overlockers were better quality, this was mentioned alongside the Brother 4234d.
It can do 2, 3 and 4 thread stitches, and the threading system is good.
It stitches fast at 1500 stitches per minute, which is the top-end for domestic overlockers.
It comes with a waste bin and separate needle threading device (it’s not built-in).
It uses standard sewing machine needles: the ballpoint HA-1SP needles (sizes 11 and 14).
There’s no free arm or extra feet, however.
3. Bernette Funlock 44
Typically £400-ish. Check Amazon’s price.
It can do 2, 3 and 4 thread stitches, and the threading system is good. It includes a waste bin and separate needle threading device (it’s not built-in).
There’s no free arm or extra feet. Be aware that you can’t use normal sewing machine needles. You’ll need to buy ELx705 overlock needles (sizes 14/90 and 12/80).
In-depth review: Brother 3034dwt (best budget)
Typically £300-ish. Check Amazon’s price.
Ideal for: people who just want a cheap overlocker for occasional sewing.
What stitches it can make
This overlocker can make the overlock stitch, rolled hem, narrow hem, mock flatlock, and blind hem stitches (here are photos).
Like all budget overlockers, it can’t do 2 thread stitches. You can only make 3 or 4 thread stitches, but that’s all most people need anyway.
2 thread stitches are good for finishing lightweight fabrics. They use fewer threads, creating a lighter stitch. If you don’t sew with fabrics like chiffon, you’ll probably never need them.
The cutting blade is retractable if you want to stitch without cutting.
Easy to thread
It has the same excellent threading system as the more expensive Brother 4234d.
There are colour-coded threading diagrams and stitch illustrations printed on the machine. This saves you from looking through your manual constantly.
The lower looper threading system, which can be horrible in other machines, is excellent. A switch pulls out the hidden lower looper so you can thread it in plain sight. This makes such a difference.
So many freebies!
It comes with an impressive number of free accessories:
- Free extension table (about £22 if bought separately).
- 3 extra feet (about £80 if bought separately).
- Free waste tray (about £24 if bought separately).
That’s a saving of £126!
I haven’t seen this many freebies included with any other overlocker.
It also has a free arm which surprisingly many overlockers don’t.
It works with normal sewing machine needles, which is a nice cost-saver in the long run. Some overlockers require special overlock needles, like Bernette and Pfaff.
Manufacturer’s warranty
Brother offers a 3 year manufacturers warranty, starting from the date of purchase. If your machine develops a fault that’s not caused by external influences, they will repair or replace it.
If you’re using your machine for commercial purposes, the warranty is for 1 year.
Best suited for occasional sewists
Be aware that this is a budget machine. It will be made with weaker metals, weaker motors, and more “relaxed” quality control during manufacturing.
This is inevitable for any cheap overlocker.
If you just sew every now and then, it’s good enough to get the job done.
Buy the Brother 3034dwt on Amazon.
If you sew often, I recommend buying an intermediate machine instead. The Brother 4234d is my favourite. It will be more durable.
If the Brother 3034dwt is unavailable:
Here are the alternatives I recommend, starting with my favourite:
- Brother 2104D (Amazon)
- Brother M343D (Amazon)
- Elna 664
1. Brother 2104d
Typically £220-ish. Check Amazon’s price.
It’s almost identical to the 3034dwt, except it’s a little cheaper and it’s missing 2 accessories: the extension table and waste bin.
2. Brother m343d
Typically £200-ish. Check Amazon’s price.
It’s almost identical too, but it comes with no extra feet and no waste bin.
3. Elna 664
Typically £269.
Finally, if even that’s unavailable, the Elna 664 is a decent alternative. It will sew the same stitches and it’s a budget price. It’s threading system isn’t as good as Brother’s, but it’s ok. You also won’t get a free arm.
At this price range, you’ll see a lot of budget overlockers from Janome, Singer, and supermarket stores. I recommend staying away from these.
Avoid: Janome’s budget machines
Janome has 3 budget overlockers that I really don’t like: the 9300dx, 9200d, and 8002dg (Amazon links).
The threading systems in these are badly designed and outdated.
It takes 5 times longer to thread the lower looper in a Janome than it does in a Brother.
No really, I timed it!
It took 40 seconds in the Brother, and 3 minutes 10 seconds in the Janome. Not good.
(The threading videos are by Ken’s Sewing Center and Syakademiet).
Side note: my criticism here is only about Janome’s budget overlockers. Their intermediate and premium ones are good.
Avoid: Singer machines
Singer’s are widely available on Amazon. Many official dealers won’t sell this brand because they think Singer’s are badly made.
A large dealer, GUR, says this on their website: “Stay away from the new Singers, although the old ones (30 years or older) are still excellent workhorse machines.”
A technician I spoke to didn’t hide his feelings. He hated them.
He thought their machines are horrible quality and not worth repairing. This came as a big surprise to me.
An overlocker seller told me not to fall for Singer’s “strong and heavy duty” branding. It’s not true apparently.
Avoid: Supermarket machines
A technician I spoke to disliked cheap supermarket overlockers. He said they’re bad quality. Think Aldi, Lidl, and John Lewis machines.
