Coverstitch basics
- Narrow cover (2 needles): classic T-shirt hem.
- Wide cover (2 needles): sturdier hems on heavier knits.
- Triple cover (3 needles): sportswear and decorative seams.
- Chain stitch (1 needle): decorative, or for basting that unravels easily.
Frequently asked questions
What is the difference between a coverstitch and a serger?
A serger trims and overcasts edges and joins seams. A coverstitch sews parallel needle lines on top with a looper underneath, used mainly for hems and binding on knits. It does not cut the fabric.
Can a twin needle replace a coverstitch?
A twin needle on a regular machine imitates the look on top, but the underside is a zigzag bobbin thread with less stretch. A coverstitch stretches more and looks like ready-to-wear.
Do I need a free arm?
It makes sleeve and leg hems much easier. Janome lists a free arm on the CoverPro 2000CPX; Brother does not list one for the 2340CV.
