Louisiana still has sewing. It is called FACTs now. My daughter teaches sewing, fashion, how to care for small children, and conflict resolution. Another teacher teaches cooking, meal planning, shopping for meals, reading labels. They have their class for 1 semester and then the students switch classes.
I helped my daughter checking out all of the machines after setting all summer last year. They were heavy metal, old, but sewed like a dream. The school had gotten six new machines for her class. They were like the older machines but didn't fit in cabinets.
I don't know anything about your add, just giving a little information.
