Incorrectly threaded

Correctly threaded

Here is how the stitching looks when the thread is not in the tension spring and the bobbin thread is pulled to the top.

Stitching when bobbin tension is not threaded

In the vertical type of removable bobbin case, it seems to happen less frequently, possibly because the case is removed to load the bobbin.

The final authority on threading the bobbin case for your model of machine is, of course, your manual.

Using the Right Bobbin

A common cause of problems is using the wrong bobbins for your type of sewing system. Many bobbins look the same or have very slight variations. However, using the wrong one can cause not only tension problems but breaking thread. A good policy is to buy the same bobbin that came with the machine originally.

In the example below, notice that the bobbin in the machine is slightly higher than the top edge of the bobbin case. As the top thread tries to come over the top to form a knot, it catches under the bobbin and jams the machine. At a minimum, this is frustrating, but there is also a chance it will end up spinning the bobbin case around and damaging it.
