100+ Stitches and 7 buttonholes

It’s true that you only need a few stitches to tackle most sewing projects, but this machine does so much more than just sew a pair of pants or a new set of curtains.

Janome includes 120 built-in stitches with this machine, which includes quilting, decorative and regular stitches. It also has alphabet fonts: European, American and Cyrillic. This model can also do monogramming, so you can personalize your projects if you wish.

The backlit LCD display and adjacent control panel makes it easy to find and select the stitches you need for your projects.

Along with a vast array of stitches, this machine has 7 one-step buttonholes.

Adjustable Stitches and Speed

The 4120QDC allows you to adjust the stitch width and length up to 7mm and 5mm respectively.

The machine also has a speed control slider for easy adjustments while you’re sewing. The slider is conveniently located underneath the LCD display, and it’s within easy reach while sewing.

The start/stop button is also convenient for those times when you can’t use the pedal.

Convenient Needle Position Memory

To make your life easier, this machine has a memorized needle up/down feature. The down position is the default setting, so you don’t have to worry about injuring your fingers while you sew.

There’s a twin needle guard, and the machine also has a stitch pattern memory capability.

Plus, the extra-high presser foot is great for working with multiple layers of fabric and bigger quilts.

7-Piece Feed Dog

For extra-smooth fabric feeding, Janome offers a 7-piece feed dog system. This allows you to work with delicate fabrics and multiple layers without worry.

Threader and Thread Cutter Plus Tension Control

The Janome 4120QDC has a built-in one-handed needle threader as well as a needle cutter. This makes threading – one thing most of us hate to do – a little bit easier. And when you’re done with your seam, you can simply use the built-in cutter to finish the job. There’s no need to drag out the scissors.

The machine also has a horizontal full rotary hook bobbin system and an auto declutch bobbin winder.

Manual tension control also gives you more control over your stitches.

Locking and Reverse Buttons

The 4120QDC comes with built-in locking and reverse stitch buttons to ensure that your stitches stay put.

Multiple Accessories

Janome doesn’t skimp on accessories, which is why this machine comes with a hard cover as well as an instructional DVD. The DVD will help you get familiar with the machine, so you can quickly learn how to use it for your next project.

Along with a cover and DVD, the 4120QDC also comes with:

  • Extension table
  • Zig-zag foot
  • Satin stitch foot F
  • Blind hem foot
  • Seam ripper
  • Needle set
  • Zipper foot
  • Bobbin
  • Overedge foot
  • Buttonhole foot
  • Sliding buttonhole foot

The extension table is great for working on bigger projects and quilts. Janome also includes a generous amount of presser feet, and the snap-on presser foot function makes it easy to switch between them all.

Lightweight and Durable

The 4120QDC is a workhorse, but it’s still travel-friendly. The machine weighs just over 22 pounds, which makes it light enough to bring to quilting classes or on road trips. It’s pretty compact in size, too, at 19.8” x 12” x 16.”

This machine can easily be brought on an RV to work on your projects while you’re on the go.

Janome machines are known for their quality and durability. This model is no exception. Many people have their machines for more than a decade before it gives out and needs to be replaced. Yes, these machines are expensive, but if they last a decade or more, they are worth every penny. The cost equates to about $100 per year if the machine lasts ten years. That’s a small price to pay for professional quality results.

Not to mention the fact that this machine is a dream to sew on. It’s solid, it’s smooth and it’s easy to work with.
