Make sure that you have the correct bobbin in the machine. I think that your machine takes 15J which is the same as my "singer confidence" machine. Size 15 looks the same size but is a little bit smaller and so it will jump out of the bobbin holder causing it not to feed correctly. Also make sure that the bobbin is threaded correctly in the holder. I just had this problem and the bobbin thread had come unthreaded in the holder. All this will make a difference in reqular sewing but seems to make a bigger difference whn FMQ. Good Luck!!!!!!!
