I wanted to put together a growing list of overlock and cover stitch settings that have been working great for the fabrics I’ve been serging with my new Babylock machine.
I mainly put this together for myself for future reference, but I thought, why not share it? Maybe it’ll come in handy for someone else too.
It’s always a good idea to use some scrap fabric to test and fine-tune the settings until you’re happy with how the stitches look.
Overlock settings
Polar fleece
- Length (L) 2.5
- Width (W) 6.5
- Differential feed (N) 1.3
- Turn the tension dial to Max + to get the looper stitches close to edge of fabric.

Sherpa boucle
- Length (L) 3
- Width (W) 6.5
- Differential feed (N) 1.3
- It doesn’t like feeding sherpa with fluffy side down. Serge one piece at a time with sherpa side up, then use a lock stitch sewing machine to join pieces. (Can serge two pieces with sherpa side inside with a bit of initial tugging.)

Double gauze cotton
- Length (L) 2.75
- Width (W) 6.5
- Differential feed (N) 1.3-1.5
- It can be a little tricky as double gauze likes to stretch or de-waffle.
Fabric: Sage colour from Spotlight

Flanelette cotton
- Length (L) 3
- Width (W) 6.5
- Differential feed (N) N
- Tension dial Max + to get the loopers close to the edge.

- Width (W) 7
- Differential feed (N) N
