JUKI MO-623 Serger

Fabrics to use with a JUKI MO-623?

The JUKI MO-623 is a flexible, affordable, semi-professional sewing machine that is compatible with over 100 accessories. By switching to different sewing needles, you can use them on a wide range of fabrics. Its robust yet gentle operation will give you professional-quality seams and finishes, no matter what fabric you’re working with.

Here’s how the Juki MO-623 Serger performs on the following fabrics:

Knit Fabrics

Because the differential feed system accommodates the natural stretch and recovery of knit fabrics, the Juki MO-623 is perfect for making stretchy seams in knitwear. Your seams will be resilient and flexible, allowing garments to move freely.

Fleece

This Juki overlocker can easily sew thick fabrics like Jeans. With high-speed operation, you can make quick work of fleece blankets and sweatshirts without missing a stitch.

Silk

When it comes to delicate fabrics like silk, the Juki MO-623 Serger delivers precise stitching that preserves the fine texture of silk. With adjustable settings to prevent snagging or damaging fine fabrics like silk.

Denim

Despite its compact size, the Juki MO-623 is powerful enough to sew through heavy fabrics like denim. Perfect for sewing jeans, totes, jackets and other denim items.

Lace

One of the most versatile sewing machines you can buy, the Juki MO-623 can also sew fine lace fabrics. It sews precise seams without damaging the delicate patterns of lace fabrics.

Fabrics NOT To Use with The 623 Serger

The following fabrics are not recommended to be stitched in your 623 Sewing Machine. While some of these fabrics may work for a short time, they can void your warranty, cause motor failure, and prematurely dull your blades. As a general rule, stick to light or medium-weight fabrics. 

• Canvas - Heavy and may shorten the life of your 623's motor (over time). 
• Leather - Doesn't work with a Serger due to its thickness and lack of pliability.
• Thick Wool - Thick wool is dense and has multiple layers, making it unsuitable for this sewing machine.

While industrial sewing machines are often specialized for one function, like straight stitching, the Juki MO-623 overlock Serger does multiple tasks in one. Affordable and priced for home and professional sewers.

Why Our Customers Love The JUKI 623

Goldtartool is an authorized dealer of Juki, which gives you the full Juki warranty and access to lifetime technical support. Our customers love the Juki 623 for these reasons: 

Easy to Operate

The Juki MO-623 is easy to operate and a great starter for home and professional sewers. Color-coded thread guides simply match the threads from the stand into the machine. There is no need to change presser feet or settings for fast seaming and built-in rolled hems.

Compact and Affordable

Goldstartool has a large selection of Juki Serger machines, like the industrial model MO-6843S, which can do six threads at once. However, the MO-623 is smaller, easier to operate, and only uses three threads. For hundreds less than the six-thread industrial model, the MO-623 is a more compact and affordable model for home and shop sewers.

Powerful and Quiet Motor

Despite being a powerful overlock machine, the Juki MO-623 is quiet. Its low-volume operation and fast stitching allow you to sew for hours and complete large projects.

Threading the Serger

Threading the MO-623 may look intimidating, but it’s actually quite straightforward. The color-coded thread guides tell you which thread goes where—needle, upper, and lower. Starting at the thread stand, follow the blue, red, and green dots for the upper, lower, and needle thread. The MO-623 holds three cones, the larger of which will have about 3,000 yards of thread.

If you’ve threaded the machine incorrectly, the best course of action is to remove all the threads and start over.

Versatile Serger Accessories

Adding accessories to the Juki Mo-623 is simple, as most add-ons do not require special tools or customizations. The top five accessories are:

1. Piping Foot - Used for: Bags and upholstery
2. Cording Foot - Adds decorations to seams
3. Elastic Foot - Makes working with elastics easier
4. Gathering Foot - Great for rufflers, dresses, and crafts
5. Blind Stitching Foot - Seamlessly adds beads while serging

What Can I Do with the MO-623 That My Regular Machine Can’t?

Seams are easy and fast; you sew the seam, trim the seam allowance, and overcast the edge all at once, and you're done with it. Your seam won’t unravel as it might with a standard domestic or industrial sewing machine.

You can also overcast a raw edge of the fabric before hemming or other stitching work. Adjust the machine for this overcast type (see the instruction manual), and the knife trims a neat, clean edge. Then, finish the hem on your regular sewing machine.

User Tips 

Remember that the Juki MO-623, like any Serger, only sews in one direction–it doesn’t backstitch like a regular sewing machine. The overlock stitch sews, trims, and finishes seams in one pass, but you can disengage the knives if you don’t want to trim your seams. It’s best to start and stop each seam with a short chain of stitches to secure the edges.
