Main Features
The Janome MyLock 634D includes several convenient functions that make serging more accessible. The lay-in threading is beginner-friendly while features like the retractable knife provide more advanced control.
Lay-In Threading System
Threading any serger can seem intimidating at first. But the Janome MyLock 634D has a unique lay-in system to make it fast and easy. Color-coded guides match up with the thread paths. And there’s a lever to move the lower looper for better accessibility when threading it.
Once the threads are through the guides, you don’t even have to manually pull them through the tension system. Just close the front looper door and turn the hand wheel to lock the threads in place. It takes a lot of the frustration and fuss out of the process.
Color-Coded Threading Diagrams
In addition to the color-coded thread guides on the machine itself, the Janome MyLock 634D has handy diagrams printed right inside the looper door. These provide a handy visual reference to the thread paths and order of threading. For those new to serging, having these diagrams onboard can save a lot of time and confusion.
Differential Feed
A differential feed allows you to adjust the relative feeding rates of the front and rear feed dogs. This prevents stretching or gathering on knits and woven fabrics. The Janome MyLock 634D differential feed has a high range from 0.5 to 2.25 for flexibility with different materials.
You can prevent lightweight fabrics like silks and satins from becoming wavy. And create intentional gathers or lettuce edges on fabrics by setting the front feed higher than the back. Having an adjustable differential feed puts more control at your fingertips.
Quick Change Rolled Hem
Rolled hems require converting the serger from a standard overlock setup. This often involves changing plates or parts. The Janome MyLock 634D simplifies the process with a quick change lever located behind the front cover.
Just flip the lever and it will move the stitch finger into the correct rolled hem position. A slider on the front tension assembly also adjusts the thread tension for rolled hemming so you don’t have to change settings manually.
Retractable Upper Knife
The upper cutting knife on sergers trims the fabric edge as you sew. But sometimes you may want to sew without cutting. The Janome MyLock 634D allows you to retract the upper knife when needed.
A knob located inside the front cover disengages the cutting knife so you can sew decorative edges without trimming away details. Once finished, flip the knob back to re-engage the blade for normal serging.
Snap-On Presser Feet
Presser feet on sewing machines snap on and off for quick changes. The Janome MyLock 634D brings this same convenience to serger presser feet.
Rather than needing tools to change feet, the Janome presser feet snap into place. Switch easily between basic overlocking, rolled hem, piping, blind hem, and more. No hunting for a screwdriver!
Stitch Length/Width Adjustment
Sergers typically offer a selection of preset stitch lengths. But the Janome MyLock 634D allows you to finely tune stitch length between 1 and 5 mm. Dial in exactly the right length for your fabric and project.
This Janome also provides adjustable stitch width from 3.1 mm up to 7.3 mm. Wider settings allow more of the fabric edge to be enclosed within the seam. Narrow settings are perfect for rolled hems.
Sewing Speed
With a maximum sewing speed of 1,300 stitches per minute, the Janome MyLock 634D is built for productivity. You’ll be able to complete projects quickly compared with regular sewing machines. Yet the Janome still operates quietly, even at top speed.

Now that we’ve covered the stand-out functions of the Janome MyLock 634D serger, let’s look at some of the benefits and drawbacks.
Pros of the Janome MyLock 634D Serger
There are several advantages to choosing the Janome MyLock 634D, from thoughtful design features to proven Janome quality.
Comes Pre-Threaded
Getting started* with your new serger can be frustrating since threading is often the trickiest part. The Janome MyLock 634D arrives already threaded so you can start sewing immediately after plugging it in and tying off the threads.
This thoughtful touch lets beginners dive into creating serged projects right off the bat. And more advanced sewers can get stitching ASAP after an equipment upgrade. The pre-threading removes a common barrier many face with sergers.

Compact Size
Sergers tend to have a larger footprint than regular sewing machines. But the Janome MyLock 634D has a petite frame measuring just 13” x 16” x 15”. It takes up minimal space whether sitting on a sewing room table or stashed in a closet.
The compact Janome is also lightweight at just over 20 pounds. Combined with the integrated handle, it’s easy to transport the serger to classes or workshops. The portable size makes it a great choice for small spaces, sewists on the go, or retreat settings.
Built-In Rolled Hem
As mentioned earlier, the Janome MyLock 634D has a quick conversion process for switching to rolled hem mode. But this serger actually provides a true built-in rolled hem. Many sergers require changing the stitch plate and other adjustments to form the rolled edge.
With a simple flip of the lever, this Janome locks all settings into the ideal rolled hem configuration. The stitch finger moves forward, the cutting blade retracts, and the thread tension adjusts automatically. You get professional rolled hems without fussing with multiple settings.
Quiet Operation
Working right next to a serger running at full speed can be deafening. But Janome’s precision engineering allows the MyLock 634D to operate quietly, even when stitching over 1,000 stitches per minute.
You can hold a conversation seamlessly over the mellow humming of this serger. The quiet operation won’t disrupt others nearby making it perfect for shared workrooms or sewing in public spaces.
Durable Construction
Janome is known for manufacturing sturdy machines built to last decades. The metal internal components and casing of the MyLock 634D serger ensure it will stay in service for the long haul. This machine provides precision stitching project after project, year after year.
Between the rugged build and 25-year mechanical warranty, Janome clearly stands behind the lasting durability of this serger. It’s worth investing a little more upfront for a serger that will still be going strong in the decades to come.
Cons of Janome MyLock 634D
While there are clear benefits, the Janome MyLock 634D serger does have a few drawbacks to consider before purchasing.
Expensive Initial Investment
With an MSRP around $800, the Janome MyLock 634D sits at the higher end of mid-range sergers. Sergers with more limited feature sets can be purchased for half this cost. So despite the durable construction, the price is prohibitive for some budgets.
Of course, there are also far more expensive serger options on the market above the Janome’s price point. Overall, you’re paying for quality construction and user-friendly operation. But the initial investment may stretch some sewing budgets, especially for a second specialty machine.
Limited Built-In Stitches
This Janome serger includes the expected overlock, rolled hem, and overedge stitches. However, there are serger models in this price range that offer more built-in stitches for flatlocking, coverstitching, and decorative finishes.
The MyLock 634D aims for quality over quantity. It focuses on doing the core stitches very well rather than packing in a wide variety. But if you want to expand your serging repertoire with more specialty stitches, this serger has limited options.
No Onboard Storage
With its streamlined design, the Janome MyLock 634D does not include any onboard storage compartments. Some sergers have small trays or pockets to hold needles, tweezers, spare blades, and other accessories.
You’ll need to keep the included tools in a separate box or pouch when not in use. The lack of storage is a minor inconvenience but could become annoying over time.
Shaking at High Speed
Standard home sewing machines and sergers are designed for periodic use rather than all day commercial production. Some users report vibration or walking across the table at the Janome’s maximum sewing speed.
This may relate more to the stability of the table or cabinet than the serger itself. But be prepared to experiment with a rubber mat or other methods to minimize shaking if sewing faster projects.
Now that we’ve weighed the pros and cons, let’s look at ideal users who will benefit most from the MyLock 634D’s capabilities.
Who is the Janome MyLock 634D For?
The approachable design yet customizable options of this serger make it suitable for beginners as well as experienced sergers looking for reliability.

Janome’s stellar reputation provides peace of mind for newcomers. And it includes plenty of user-friendly features like snap-on feet, retractable blade, and storage compartments.
The Janome offers room to grow as your skills progress. You won’t outgrow this machine as your projects become more advanced. And it will prepare any beginner to upgrade to a coverstitch or multi-needle serger someday. Overall, it’s a perfect starter serger that won’t leave you with buyer’s remorse.
The Home Sewist
Home sewists looking for a quality overlock machine will find satisfaction with the MyLock 634D. It’s compact for space-saving. Quiet for maintaining a peaceful environment. And adjustable for handling a wide range of fabrics and garments.
From serging stretchy activewear to rolled hemmingdelicate silks, this Janome can do it all. The durable metal construction can withstand years of regular use and stands up to thick fabrics like denim. For the home sewist seeking reliability above bells and whistles, the 634D hits the mark.
The Advanced Serger
Just because it’s beginner-friendly, advanced sewists shouldn’t overlook the Janome MyLock 634D. The precision stitching and powerful motor can handle heavy sewing demands. Janome sergers are workhorse machines built for daily use in professional settings.
If your serging needs are straightforward – primarily overlocking, edge finishing, and hemming – this machine won’t leave you wanting. The adjustable cut width and presser foot pressure provide the customization that advanced sewers desire. Reliability and stitch quality trump fancy extras for many experienced sergers.
Janome MyLock 634D Accessories
In addition to the serger itself, the 634D comes with a selection of accessories. You can also expand the machine’s capabilities with optional add-ons.
Bonus Accessory Kit
Purchasing the Janome MyLock 634D includes a starter kit with handy accessories including:
- Tweezers – Grip threads to thread guides easily

Extra Upper Knives
The upper cutting knife on sergers is a consumable part that needs regular replacement. Purchasing additional blades to have on hand ensures you can quickly swap a new one in when cutting performance declines.
Machine Cover
Although the 634D lacks onboard storage, investing in a fitted machine cover is wise. Protect your serger from dust and damage when not in use. Covers also help restrict fibers and lint from collecting inside the serger’s working parts.
Choosing the Janome MyLock 634D serger brings you stellar construction and user-focused features. But how does it compare with leading competitors?
Janome MyLock 634D Alternatives
