I learned to sew from my mom and from a sewing class when I was 8 years old. But that was basic sewing and making stuff from patterns. I sewed all the way through high school, dresses, skirts, pants, bathing suits, etc.
I took time off from sewing while in college. When I had my kids, I sewed clothes for them.
Last year when the last went off to college, I decided to start quilting. I read websites, watched youtube videos, checked out books from the library, etc. I never took a quilting class, so my construction techniques are all trial by error.
Quilting is still stitch in the ditch, but I'm getting ready to branch out.
So my answer is a taught sewer, but a self taught quilter.
