My tensions being really weird. I sell patches on etsy and ran out and the last batch i made was in december, but im pretty sure it worked just fine with the normal tension setting. I un threaded and re threaded the top thread and wound a new bobbin, and turned the tension from 4 to 3, which made the bobbin loops on the top less bad but it still won't sew right. I do have a different brand thread now thats a bit thinner and black instead of white in the bobbin, but i used that brand for other parts of the patches before and it worked fine. I don't feel like trying to set up another 6x10 with tearaway (why are the big hoops ovals?) right now so i might switch back to the white bobbin later, but i was wondering if you guys had any other suggestions
