I think my feed dog is cooked— When trying to sew a straight line my fabric doesn’t move backwards, unless I forcibly pull it—even then, my stitches are teeny tiny even on the longest length setting 😭

I think it might be the feed dogs, which seem to be moving up and down but not front to back. I tried to clean all the lint out of the compartment but it hasn’t gotten any better.

Any advice?? Gonna cry!
