I had the good fortune of taking a full year - or maybe it was two, don't remember - of sewing in high school (definitely not the college track for me) Although I do not remember making any pattern alterations...don't think I needed any in those days... I did learn many construction and tailoring skills that have been valuable throughout my life. I will never forget that teacher. I did not take up quilting until my late 50's, but have recently gotten back into garment sewing after a very long hiatus.
