Serger vs. Coverstitch Machine — What's the Difference?

A serger and a coverstitch machine are designed for different finishing techniques.

Janome FA4 Serger: Trims fabric edges while creating overlock stitches that finish raw edges and can construct seams.

Coverstitch Machine: Creates stretchy hems and decorative coverstitches, like those commonly found at the bottom of T-shirts.

The FA4 is an overlock serger, making it an excellent companion to your regular sewing machine or a dedicated coverstitch machine.
