Definition & Meaning of "sewing roulette"

What is a "sewing roulette"?

A sewing roulette, also known as a tracing wheel, is a tool used in sewing and dressmaking to transfer markings from patterns onto fabric. It consists of a handle and a wheel with sharp teeth or edges. The wheel is rolled over the pattern, and the sharp teeth or edges make small perforations or marks on the fabric. This technique is used to mark the placement of darts, pleats, pockets, and other design elements. The marks can be transferred to both sides of the fabric, making it easier to align and sew pieces together accurately. Sewing roulettes come in various sizes and shapes, and they can be used on different types of fabric, such as woven or knit, depending on the size and shape of the teeth or edges on the wheel.
