RevolutionAir® Threading
Threading a serger doesn't have to be intimidating. Baby Lock's RevolutionAir® Threading system helps streamline needle threading with convenient push-button operation. Combined with easy looper threading, Serenity is designed to make setup quicker so you can get to the creative part of serging sooner.
No Traditional Tension Adjustments
The Automatic Thread Delivery™ System helps take the guesswork out of balancing serger stitches. Instead of constantly adjusting individual tension settings, select your stitch and let the system deliver the appropriate amount of thread. This makes moving between different fabrics, threads, and techniques easier and more approachable.
Snap-on Needle System
Needle changes are quick and convenient with the Snap-on Needle System. The tool-free design helps simplify routine needle replacement and makes it easier to prepare your serger for different fabrics and projects.
Digital Speed Control
Adjust the machine's sewing speed with the touch of a button. Whether you're learning to serge, working around curves, handling detailed areas, or ready to move quickly through long seams, digital speed control lets you choose a comfortable pace for the project at hand.
Needle Up/Down Positioning
Choose whether the needle stops in the up or down position for added precision. Leaving the needle down can help maintain your position when adjusting fabric, while needle-up positioning makes removing or repositioning a project convenient.
Differential Feed for Better Fabric Control
From stretchy knits to lightweight woven fabrics, differential feed gives you greater control over how fabric moves through the serger. Use it to help prevent unwanted stretching or puckering, create smooth professional seams, or intentionally gather fabric for creative effects.
