Had a weird thing happen yesterday. Kept having bumpy stitches. Reset bobbin. Replaced bobbin. Rethreaded upper thread. Replaced needle. Replaced bobbin case with my spare! Took apart and cleaned out bobbin case area and auto scissors area and oiled machine. Broke a needle. Broke another needle, which shattered and flew above my glasses, which were sliding down, and into my eye! Reconstructed the pieces and lined them up with a new needle to be sure I got all the pieces out of eye! Lessons learned: keep eyeglasses adjusted tight so they don't slide! Sometimes a whole package of needles is barely crooked and causes funny, bumpy stitches on the top side of fabric. Whew! It was a puzzle! (Eye is okay, just a bit red today.)
Glad your eye is ok.
