Please Note: Many sewing machine feet are interchangeable, but they are not entirely universal. To know if a sewing machine foot will fit your machine, first determine if your machine is high shank, low shank, or another style. Most home sewing machines are low-shank style. Only low-shank feet will fit a low-shank machine, and only high-shank feet will fit a high-shank machine. Then, determine the presser foot's attachment style: does the presser foot screw or snap onto the machine? As long as you choose a foot with the correct shank height and attachment style, many brands and types of presser feet may be applicable. However, some brands of sewing machines like Bernina may have a different presser foot system that is not interchangeable with other brands of presser feet.
