One of the marks of a professional seam is a perfectly balanced stitch.
When you are working with a sewing machine, there is really only one tension you have to worry about: the top thread (although some machines allow the user to adjust bobbin tension as well). Sergers, however, are a different story. With up to three wo needle threads and up to two looper threads, many first time users throw up their hands in frustration. How does one make sure that each of the upwards of five threads works together to make the perfectly balanced stitch?
What even IS a balanced stitch?
