Janome 634D MyLock Serger Review

Janome 634D MyLock Serger

Well, this is not your typical sewing machine. It does not even look like regular sewing machines and operates quite differently. This is because the Janome 634D is not a sewing machine; it is a Serger.

Therefore, if you find stitch allowances fraying at the edges after a short time or if they look bad to your eyes, this is the machine that you need. It is specifically designed to finish these allowances by wrapping multiple threads around the fabric’s edges, ensuring that they do not unravel in the process.

This Janome 634D review looks at the features that make this unit one of the market’s best sergers

Features of the Janome 634D Sewing Machine  

Up to 4 thread overlock

This is arguably where the strength of this machine lies. It can be used to create overlocks with either 2, 3, or 4 threads, and this ensures that you have more options to wrap around the edge of the fabric tightly.

This is made possible by the machine’s twin needles and twin loopers, each requiring its thread. However, you can use two threads by threading only one needle and one looper, three threads by threading 1 needle, and both loopers or 4 threads by threading all needles and all loopers.

Of course, threading all 4 is better because it will produce the best overlocks, but you can thread as you please.

Easy to use and maintain

This unit is elementary to use. Other sergers normally require their plates to be changed when switching from conventional overlocks to creating rolled hems and vice versa. However, this model requires you to flip a switch when shifting between the two modes, and that’s it.

This is coupled with snap-on presser feet that make it easier to shift completely to the new mode and back.

In terms of maintenance, the machine has two covers that open up the internal mechanisms underneath, enabling you to clean and oil it for optimal performance.

Fast, quiet, and compact

This machine has a top speed of 1300 stitches per minute, which makes it very fast and good for completing your projects in a short time.

This is made possible by its powerful motor that operates quietly and smoothly to deliver these fast speeds.

Final Verdict

With this machine, you can easily go from being a simple sewer to a professional one. However, since it is a serger, it might not be easy to use by a beginner who is completely new to this craft, especially those who do not even experience using a sewing machine.

That said, if you can get your hands on this unit and be determined to learn about how it works, it might drastically improve the quality of your projects.
