I basically taught myself to sew. My grandmother sewed doll clothes with us when she visited (on a machine SHE bought to keep at our house LOL) and my parents didn't sew at all. They redid the curriculum while I was in middle school so I missed the sewing class.
I mostly learned to sew when I was a color guard instructor sewing flags all night between competitions. Cut my teeth on lame' and ripstop nylon!
(Tip on sewing lame': wear a mask. Those fibers will decorate your lungs very nicely otherwise.)
