The TRUECUT 360 Circle Cutter is designed to make clean fabric circles for quilting and craft projects with controlled rotation with consistent, measured results. Set the circle size using the built-in markings, lock the center point, and rotate to cut circles from 2 to 12 in (5.1 to 30.5 cm). The design helps prevent fabric bunching while cutting, and the blade cartridge can be replaced when the edge dulls.
