I just bought a Singer 15-91 to do my FMQ on. I am new to FMQ. I've been doing it on my newer little Brother SE-350. I'm hoping it will be easier on the vintage Singer. I love the way the Singer sews, but I am having a little trouble with the settings when I FMQ on the Singer. The upper thread breaks occasionally. I am not using machine quilt thread, would that make a big difference? Any tips on tension and stitch settings?
