Mom taught us (myself, my sister and my brother). I then took more than a few years of sewing (and other stuff) in school and learned more. Stopped sewing for a long time, picked it up again when I first got married and got a sewing machine as a wedding gift. Sewed more garments for a good number of those years then dropped it again. Started sewing again a few years before my second marriage and again I got a new sewing machine as a wedding gift.
7 years later, "Spare" Sewing machines #3 and #4 fortunately came without spare husbands!!
