Adjustable Differential Feed Ratio

The Brother Designio Series DZ1234 Serger has an adjustable differential feed that allows it to stitch various materials, including delicate and thick ones.

Thanks to the several built-in stitch choices, the adjustable differential feed guarantees beautiful ruffles or smooth stitches, even on highly elastic materials.

The movement ratio between the front and rear feed dogs is controlled by an adjustable differential feed, which helps feed the fabric smoothly beneath the needles.

When generating gathers or ruffles on the machine, adjusting the differential feed settings makes all the difference.

By pushing a lever on the serger’s side, you may immediately change the pace of either feed dog beneath the presser foot.

This option prevents puckering on sheer or lightweight fabrics as they move beneath the needles, in addition to generating precise gathers.

Stitch Width Control

You may vary the stitch width from 3 to 7 millimeters, allowing you to tailor the stitch to your project. It’s critical to alter the stitch width when dealing with delicate or sheer materials to get flat stitches.

Color-Coded Threading

Regardless of the thread kinds, the serger is color-coded to make threading a snap. The needles and the upper and lower looper threading have an easy-to-follow color-coded guide on the front of the machine. The system makes the process of learning how to thread a serger.

Interchangeable Feet

A gathering foot, a piping foot, and a blind hem stitch foot are interchangeable on the DZ1234.

The gathering foot collects one length of cloth while attaching it to a flat fabric and completing the edges simultaneously.

The piping foot guides are small, making installation easier and holding zippers in place.

The blind hem stitch guides the cloth under the foot to form a blind hem that is almost undetectable.

Free Arm

This Brother model allows you to operate on a flatbed surface or switch to a free arm work area quickly and easily. Sewing sleeves, collars, pant legs, and little children’s things are simpler with the free arm.

When you want to provide a clean, professional finish to parts that are normally difficult to reach, just remove the flatbed extension.


The needles used in the DZ1234 are the same as those used in sewing machines. This is handy for the user and makes needle shopping easier.
