I am so aggravated with this thing!!!!! It's me, of course, and not the machine. I took the bobbin holder/case thing out and can't get it back in for the life of me. There is still something hanging up on the bottom. I am going to call the repairman tomorrow and see when he can operate on her! I want her to work so bad, I can't stand it, but looks like I'm going to have to wait a few days. She sure is clean, though, as are all of her parts and accessories. I got on such a roll, that I cleaned bobbins and attachments for a couple of my others, as well. I have clean machine parts on towels all over the counter!
