A sewing machine to which a circular stitching device configured to anchor a sewing workpiece in a rotatable manner includes a feeding device, a sewing device, a processor, and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, cause the sewing machine to execute the steps of specifying a distance between an anchor position and a needle drop point, changing first feed amount data into second feed amount data based on the specified distance and a length of a stitch pattern, specifying an actual amount of movement of the sewing workpiece, and revising the second feed amount data for at least one stitch, among stitches of a plurality of iterations of the stitch pattern, that is not yet formed, based on a difference between the specified actual amount of movement and a planned feed amount indicated by the second feed amount data.
