Nobody taught me.
I would love to be able to say my mom or grandma taught me, but alas, I'm self-taught. They taught me lots of other neat things, but not sewing. Mom
hates to sew. (I did have a sewing class in junior high, but it didn't teach me much at all---teacher was a great seamstress who couldn't teach to save her soul..) And no one in my family ever quilted. I think I'm a mutant.
