The walking foot is a moving feed system that holds and moves fabric between the presser foot’s upper feed dog and the machine’s lower feed dogs to better control difficult fabrics as well as multiple layers of fabric. The walking foot is great for sewing when matching prints or plaids or when fabric drift is an issue or quilting.
