I find that when my tension goes wacko, this is usually the issue--and hitting a seam bump will sometimes pull it out.. I also have found that some of the finer,"slicker" threads, like Glide come off the thread spool faster and mess with tension--so those thread spools get a little stocking cap---you can buy net ones, but I use the toe of hosery with the tip cut off so thread can pull though. It does not have to be tight. Also the Towa gauge, used on every bobbin, sure has helped end the constant guess work on tension.
