My bobbin was inserted correctly; my problem was that I didn't know there was a tiny hook hiding inside, and because I wasn't putting tension on the thread as I curved around toward the cutter, it wasn't catching on that hook. She said to hold down the bobbin and pull the thread a bit, and that seems to have cured the whole issue (at least in the hour I've gotten to sew since then). It even seems to have solved what I thought was an upper tension problem, too!
