Tension problems -- needles breaking! Help
Somehow I seem to have gotten my thread tension misadjusted. I've broken five needles over the last few days of trying to sew -- thread breaks; fabric bunches up because one thread is too tight; needle breaks.
The manual with my Wizard (about 50 years old; I've had it for a year and sewn only on it) suggests that the tension isn't right -- but it doesn't really say what to do to fix it.
I was getting a lot of extra top thread sticking through the bottom, so I tried making the top tension tighter (which I thought would be a higher number), and now the top thread is flat and tight on top. I didn't do anything to the bobbin tension, at least I didn't try to (just loaded the bobbin and put it in like always).
And suggestions? Thank you!
