Machines & tools

Cumulative strain on hands, wrists, neck, or shoulders from repetitive sewing motions and poor posture, managed through breaks, stretching, and ergonomic workspace adjustments.

A narrow, tightly wrapped edge finish produced on an overlocker by adjusting the stitch finger and tension so thread coverage rolls the raw fabric edge under.

A curled, funnel-shaped presser foot that folds a narrow raw fabric edge twice as it feeds, producing a tiny finished hem in a single pass.

A rotating mechanism beneath the needle plate that catches the upper thread's loop and carries it around the bobbin case to form a lockstitch.
