It was a 1971(? I think) Kenmore of all things. I had no idea Kenmore even made sewing machines, but apparently they did. I still have it. I couldn’t get the zipper foot to work and the proverbial straw was that not only could I find no help online, but the guy at the repair shop said “Why are you bothering?” Although that did rub me the wrong way, admittedly. I took it to a different shop and they said essentially the same thing but in a much kinder and gentler way. (I bought a new machine from them instead of the first guy.) I decided I wanted something I could at least find help for on YouTube, and in fact I have watched videos a few times when I couldn’t figure something out… or whenever I want to do a blind hem because I can never remember how to do it.
