While I was sewing the machine stopped properly threading, so I tried rethreading and checking bobbin tension, but it looks like the needle is just not reaching the bobbin, so it is missing the bobbin thread. How did this happen (mid-sew, no less) and what can I do to fix it? This is on a Pfaff hobby 309

Have you changed your needle? If so do a visual check on the bobbin case area.
-With the bobbin door open, so you can see the bobbin case, turn the hand wheel towards you and you should see the needle come down and the top thread catch and loop around the bobbin thread and pull both to the top.
-If if is not, it is going to be your hook to needle timing or clearance.
When the needle is on the up movement, the hook should pass right above the eye of the needle.
