Happy learning in the New Year!
So I started my new year with a learning experience.
Did you know that a bit of lint can quite effectively block the opening for your bobbin thread to exit the bobbin case? Well not only that but it can be most definitely difficult to retrieve. It had apparently very firmly wedged itself into that spot and wasn't about to move! Between digging repeatedly with the point of my trusty seam ripper and "sawing" in the opening with a few inches of waxed dental floss it finally released all of it.
I was reluctant to take the bobbin case apart as I was not sure I would know how to determine proper tension setting upon reassembly. Very glad I didn't have to learn that part!
