I have tried: changing the needle, and the size of the needle 11 to 14, it is Schmetz embroidery , changing the WSS from Vilene to old standby, changing the thread, I throughly cleaned the top and bottom of the machine, I can't find any lint, or loose threads. I added a drop of oil to the top lifter where I always do. It is one of Yoriko's designs, a football jersey, so I knew it should be fine. I just can't seem to figure it out. I'm using the same thread on top and bottom, I tried thinner thread on the bottom at first, but changed to the same. What am I doing wrong???? What else can I try???
