It seems like this always happens to me when I'm frustrated or in a bad mood. When I am in these moods, sewing relaxes me but it seems it is easy for my machine to mess up, usually it is just me creating the problem. So, I don't make anything for my customers when I am in a down mood. You should read Buttercreamcakeartists post about her machine and feed dog problem...lol. She has had endless problems..when one thing started tearing up then everything did.
