reading about thread jams in 221s. just teach yourself to
NEVER turn the wheel backward, just towards you. hold the tails when you start sewing. It's the sound of the vintage
machines that I like. soothing,a well-tuned machine at work.
my Bernina (that I really love) is now used only for zig-zag, etc. I do miss the neeedle-down and knee-lifter. I have a 1947 model 201. just clean them, oil them. you can take care of almost any repair yourself (because there aren't many).if you ever see one, get it, you won't be sorry. they can be had for $50-200.
