Question

I need instructions on retiming my machine. My machine all of a sudden won't pick up the bobbin thread. Have cleaned, etc. to no avail. Thanks! Sheryl

My machine broke a needle- I had just been operating it in overcasting stitch, and the shuttle area was louder than usual, so I took it apart and oiled it, and now it doesn't pick up the bobbin thread at all. I've checked and rechecked the threading, shuttle etc, but it is still not stitching....
