A sewing machine includes a sewing portion, a movement portion, a processor and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include acquiring pattern data indicating positions of a plurality of needle drop points to sew a pattern, acquiring a position of a sewing start point of the pattern, performing first correction, performing second correction that uses the acquired position of the sewing start point as a base point, and corrects the pattern data, by changing, by an acquired change amount, the positions of the plurality of needle drop points represented by the pattern data corrected by the first correction, and controlling the sewing portion and the movement portion and sewing the pattern on the sewing object, in accordance with the pattern data corrected by the second correction.

Sewing machine and pattern alignment method

A sewing machine includes a movement mechanism, a swinging mechanism, a presser device, a guide portion, a processor, and a memory configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include acquiring pattern data used for sewing a couching pattern in which a plurality of motifs are continuously arranged. The motif is configured in a predetermined shape by a plurality of stitches including a main stitch and a sub-stitch. The processes include correcting at least one selected from the group of a start point position and an end point position of the main stitch of one of the motifs, such that the length of the main stitch of the one motif is longer in a second case than in a first case, and driving the movement mechanism and the swinging mechanism in accordance with the corrected pattern data.
