lockstitch

A sewing machine creates a strong lockstitch on a piece of denim fabric.

Definition

Noun: A type of machine-made stitch in which two separate threads, one from above (the needle thread) and one from below (the bobbin thread), are interlocked or twisted together at the center of the material being sewn. This creates a secure, durable, and non-raveling seam, making it the most common stitch in modern sewing machines.

Usage

The term "lockstitch" is used to specifically describe the stitch formation and the resulting seam. It is a technical term common in sewing, tailoring, and textile manufacturing. - It functions as a countable noun (e.g., a lockstitch, tight lockstitches). - It is often used attributively as a noun modifier (e.g., lockstitch machine, lockstitch formation).

  • Most household sewing machines create a basic lockstitch.
  • You can adjust the tension to make the lockstitch tighter or looser.

Advanced Usage
