There are a lot of activities involving needles and thread and textiles, whether it be practical garment-making, quilting, upholstery and drapes, or arts and crafts. It is all way beyond mending ripped hems and sewing on buttons! I can sew and quilt and the rest of it, but if I needed a suit jacket altered I would run right to the tailor! We all have our limits.
Fads and styles may change but I can't see quilting fading away ever.
