I have just picked up my machine again from my dealer because the tension was way off. There was no charge as usual. However she told me that her tech whom I really like had told her that the 2 of us (my dealer) & me still are not threading the bobbin properly. We must now start using the slotted end of the white poky stick that comes with the machine. I can feel the thread engaging when I thread it but it does pop out of the square tension box I have noticed when I free motion quilt my heavy pieces. Already my machine does not pick up the top thread unless I engage the bobbin first (does anyone else have a machine that has this quirk?)
I have had my machine for more than 2 years & love it but I must say there are some days my trusty 430 is a much better friend.
I am looking forward to any positive tips that you can give me.
