Maybe you obtained basic sewing skills in "Home Ec" class during middle or high school and made yourself a locker caddy, or possibly your mother or grandmother taught you how to sew a pillow or stuffed animal as a child.  If so, these basic skills have potentially afforded you the capability of taking a shirt in at the sides or top stitching a patch on the knee of your pants.  However, unlike the first sewing machines which were industrial and used for speed and single function use, home sewing machines were created for portability and convertability, allowing you more options than just a few basic stitches. Home sewing machines can do a large variety of tasks simply by changing the foot of the machine.  Despite potential basic knowledge of sewing machines, many of us have no idea what any of the items below will allow us to do.  This post explores the function of the long "L" shaped tool pictured on the top right of this flat lay of vintage household sewing machine feet.
