Your projects aren’t limited to apparel either. With the Juki MO623, you can create crafts, accessories, and even home décor. For your ease, Juki has put in a color-coded threading system to make the machine easy to thread. Simply follow the color coded path to get your threads into the guides.

Tension adjustment is much easier with the MO623 as well, thanks to the 1-rotation tension dials. Normal positions are highlighted to give you simple and consistent adjustment for your tensions.

This Juki Serger offers an upper and lower knife system to make cutting easier, smoother and more consistent. The entire system is run off a one drive that is dedicated to this role to provide  you with a very even and smooth cut.  

Rolled hems are also a veritable breeze – all you have to do is flip a switch and you're ready to create beautiful rolled hems on your Juki MO623 Serger. The presser foot has multiple functions and can sew overlock stitches, add tape, add elastic or ribbon, or even add sequins. The presser feet snap on, meaning you can change out a presser feat in a snap – literally!

Seam allowances are made much easier with the built-in seam guide that takes the guesswork right out of your sewing.

    Small machine, easy to use. Works well with stretch and regular fabrics.
    But on thin fabric the seam looks different than the one done on industrial machine.

    Juki serger

    Posted by P. Kehler on 9th Oct 2017

    Purchased the serger as a gift for my wife and she was very excited! Works very well and the price was the same or better than ANY other site, nice not having to shop around. It did everything it said it did and was not a disappointment. The video it came with was a little outdated but very quick and easy in describing what it can all do. I purchased Juki because of the quality in the name brand and not the functions, but from what I hear from my wife it does everything she could need. If you buy the extra feet (like all sergers) than it could do even more. Value for the money, compact and well made.

    Perfect home machine

    Posted by julie meyer on 9th Oct 2017

    I was looking for an easy-to-use home serger for an easy-to-accept price. This was a great choice. I've only been using it for a month now, but it does everything I ask it to do and I feel like my ability to produce clothing has expanded and is faster.
    Definitely recommend this if you are looking for a serger to use at home.
