General purpose foot is also called the straight stitch foot, and the standard foot. This foot comes with all sewing machines and is therefore considered standard to all machines. This presser foot is the most versatile of all presser feet because it can be used with such a wide variety of stitches. The foot does not look very different from sewing machine manufacturer to manufacturer and has a very simple design making it easily recognizable. Depending upon the machine, the foot may be one that snaps onto the shank of the machine or one that is attached by screwing it onto the shank.
