I had home ec and the first sewing project we did was a shirt with interfacing! yikes. Then I made some gauchos. lol.
Our local high school has home ec classes, but they also have an agriculture program.
I can't remember when I couldn't sew, though. To me, it's just like following a recipe. I have quite often just free-styled what I needed (not clothes!). I'm getting ready to make some insulated bags for my new business, if I can find a good fabric for them. I've already constructed them in my mind.
