A sewing machine, comprising:

• a bed;
• a feed unit including a feed dog disposed at the bed, the feed unit configured to drive the feed dog to feed a workpiece in a feeding direction;
• a sewing unit including a needle bar, the sewing unit configured to form stiches by moving a needle held by the needle bar up and down relative to the workpiece fed by the feed unit, the stitches representing a pattern including pieces of a design that are repeatedly arranged in the feeding direction, the design including a plurality of line segments, at least one of which extends in a direction crossing the feeding direction;
• a projector configured to project a projection image onto a projection area on the bed;
• and
• a controller configured to control the feed unit, the sewing unit, and the projector;
• the controller configured to perform steps comprising:
• determining a pattern from multiple patterns, as a first pattern;
• generating the projection image including a first image representing a sewing image of the first pattern in a sewing expected size thereof, the first image being located toward an upstream side in the feeding direction from a position corresponding to a needle drop position in the feeding direction;
• causing the projector to project the generated projection image onto the projection area;
• and
• controlling the feed unit and the sewing unit to sew the first pattern on the workpiece in the sewing expected size based on pattern data for the first pattern.
