Ah, Miz Johnny, my thread never tangles, but on a 301 the bobbin runs out often when FMQ. Happy New Year to y'all.
AnnieRose's (301) latest - 1000 yards of thread and not one bird's nest or stitching issue. She may not be a pretty treadle, but she knows how to sew. BTW, the blue and gold were high school colors. I didn't just pull fabric from my stash. My son was pleased.
