Sorry, I don't know what kind of machine you have and I did not see
anyone mention the bobbin case tension (sorry if I missed it). But, if
your machine has a removable metal bobbin case, have you checked or had
the tension on it checked recently? Bobbins with tension screws need
periodic checking and adjustment. There are protocols and gauges for
doing this. I keep a second bobbin case, for instance, that I use for
decorative threads one normally would not use in a bobbin so I can
adjust it as necessary and not have to touch my normal bobbin case.
They always check the bobbin tensions on my Bernies when I take them in
for their periodic check-ups.
