Machines & tools

A presser foot with a guide pin or brush that stitches over a raw fabric edge to prevent fraying, mimicking a serger's edge finish on a standard machine.

A machine that simultaneously trims a fabric edge and encases it in interlocking looped thread, using multiple threads, needles, and loopers to finish seams quickly.

The upper and lower knives on a serger that trim the fabric edge just ahead of the needles as the seam is stitched.
