AAARRGGHH I just spent more than 4hrs with a featherweight that kept breaking the top thread. I had that baby apart a dozen times. I even took the tension apart 3x. I looked up to see if I could find some info and again went back and took the tension apart. then I decided that I was going to sit down and read everything about FW that has been posted here on the QB. and all that time I was threading from the left to the right and it was suppose to be the right to the left!!!! it has a beautiful stitch. AARRGGHH. at least I know now. sigh
