I am totally lost. I set up my serger according to the manual for a rolled or narrow hem. For some reason the thread from the upper looper looks like it overshoots the right needle. (See photos.)
The upper feed thread seems to go a random depth and looks loose (?). I keep playing with the tension, but am not getting any good results.
What am I doing wrong? How can I fix this?
Thank you in advance for helping a serger newbie like me.
