Add to that - I was sewing some filmy polyester and changed the throat plate to the one-hole one - forgot and set the needle to the far left position - broke two needles! before I remembered that I needed to put the zigzag throat plate in!
Good suggestions about leaving notes to oneself when leaving a project. I have some UFOs that are mysteries now. A two minute note to myself would have saved me hours of wondering "what was I doing here" - Also need a reminder about which ruler I was using.
