Cover Stitch Narrow
This professional Cover Hem stitch is a necessary requirement for today's sewing.
The stitch is often seen in ready-to-wear garments. Two needles create parallel
rows of topstitching and one looper sews an edge finish on the underneath side.
Depending on which needle position is selected, the width can be 5.6mm wide or
2.8mm wide.
