ok, i replaced the needle, thread and read the instruction booklet--the wheel doesn't let the needle go into the hole to catch the bobbin thread. I have spent almost 1 1/2 hours trying to re-do everything I can think of but to no avail. It's almost as if it;s locked up but the thread does pull through when I pull it.I wish I knew what caused this because I did make 2 lap quilts before happened. I will try anything but we don;t have any repair shops around here, so it's really up to me to fix!!!
