suddenly loops appear on top
I need help. What am I doing wrong? I free motioned (all over meandering) the flannel top with flannel backing with off white thread all of the off white parts of the quilt. While I am not great, it came out okay. Now I am trying to do the colored parts with same type of thread (wt and manufacture) and I am getting eyelashes on the top. I cleaned the machine, changed needles, re-threaded and put in a new bobbin. I have a QCP 9400 so I don't know how to adjust the tension.
Any suggestions? Thanks for any advice you can offer.
