I kept re-threading every time she broke the thread (which was every few stitches), finally got so frustrated I walked away after calling her a few choice names! The repairman who worked on her last week told me that I should be using a universal needle, size 90, instead of the size 75 called for in my manual. I figured he must know what he was talking about so that was what I was using. I put a size 75 back in and there was no more problems! Just goes to show that not all repairmen know what our machines like!
