Gathering
Using the differential feed a single layer of fabric can be gathered be-
fore sewing it to a garment.
For example, sleeve heads and lower edges, yokes, lace edging or
frills.
Adjustment:
• Stitch - 4 thread overlock
• Differential feed – 2
• Stitch length - 3-4
• Cutting width - 2-3
Increase the needle thread tension (6-8) for a tighter gather.
Note:
When sewing without differential feed, turn the adjustment knob to "N".
