1. A method for guiding a sewing operation of a sewing machine, the sewing machine having a needle configured to periodically pass through a workpiece by reciprocal movement, the method comprising:
selecting one of one or more stitch objects having stitch data associated therewith, each of the one or more stitch objects defined by a geometric pattern;
analyzing the stitch data of the one of the one or more stitch objects to identify one or more lines forming the geometric pattern;
sewing, onto the workpiece with the needle, at least a portion of a sewing material in a direction defined by a first of the one or more lines forming the geometric pattern;
detecting the at least a portion of the sewing material sewn onto the workpiece in the direction defined by the first of the one or more lines; and
activating a primary light source to project a first of one or more guidelines onto the workpiece, the first of the one or more guidelines to be aligned with the first of the one or more lines to provide a direction of a second of the one or more lines forming the geometric pattern.
