Self taught here, too. My Mom sewed for other people when I was little, and she taught me to sew ( commercial Wilcox and Gibbs machine) before I started elementary school.
Made my own clothes from 4th grade on, and watched my Mom and grandmothers do quilt piecing.
Did not take up quilting on my own until my own kids were grown, and by then, my Mom and Grandmothers were gone.
Have gotten magazines and books, and endless information online.
