I had one semester of sewing (and one of cooking) in junior high, nothing after that, and I don't think it was offered. I learned to sew mostly on my own with a little help from my mother, and only started quilting a few years ago. Back then (in the dark ages) it was necessary to sew because "store bought" things were much more expensive than home made. That is no longer the case, and I think that is why people don't sew as much, except as a hobby. I think 4-H has always been the main opportunity for young people to learn to sew.
