Hi all, me again. After spending a small fortune on needles and thread and making more “sandwiches” than a lunch lady

I have determined that my machine is not ambidextrous. It only behaves if I fmq left to right. If I go right to
left the thread immediately skips and breaks. I saw a video by Leah Day on this subject but I’ve never heard of anyone else having this issue. I just finished a table runner which I quilted without breaking thread...but I only moved the quilt left to right. The constant turning was a pain and I’m limited in my patterns, but I got it done. Has anyone else dealt with a situation like this?
