What is a rotary cutter used for in sewing?

A rotary cutter is a specialized tool used in sewing primarily for cutting fabric with precision and efficiency. This cutting tool consists of a circular blade that rotates as it is pushed along the fabric, allowing for a smooth and clean cut.

Using a rotary cutter is particularly advantageous when working with multiple layers of fabric, as it can slice through them simultaneously, which is more difficult to achieve with traditional scissors. The design of the rotary cutter helps to ensure that the edges of the fabric remain crisp and unfrayed, contributing to better seams and finishing in sewing projects.

In contrast, other options involve different sewing tasks. Stitching fabric pieces together is done with a sewing machine or needle and thread, creating seams. Creating hem edges involves folding and sewing the fabric's edge, typically using a sewing machine or hand-sewing techniques. Trimming loose threads is generally accomplished with scissors or thread snips. Each of these tasks requires different tools and techniques that do not involve the rotary cutter's unique cutting capability.
