That advertisement took me down memory lane. I took my first sewing class at our local Singer store in 1954. I don't remember what kind of sewing machine I used but it was the first electric machine I ever sewed on. The scariest part was actually making the first cut into the fabric. I still have a scrap of that fabric that I found in my mother's trunk. I do have a couple of the Singer Zig Zag attachments so it was interesting to see them used.
