SSSSOOOOOOO what if they do get magnetized? I just know some bobbins are better than others.
I think OSMGs might have as many myths as the rest of us that they propagate. He'd said to me that a magnetized bobbin tended to "stick" and loosen, causing inconsistent tension. I'm not sure I believe that.

I wonder if that's why I've heard that they wear bobbin cases out and replace them "once a year" from a few people with "modern" brother machines who sew a lot. And I mean a LOT. It seemed strange to me, but if they're using metal bobbins and a plastic case, maybe?
