I don't still have the Phoenix - someone on QB has one - they thread through a hole in the top of the bobbin case. Maybe yours has one, too. You might search Phoenix on here and see if you can get it to come up. Maybe it is similar enough to be of some help. The Phoenix is a wonderful machine. I let mine go to a little gal who deserved a good machine. I'm just betting your machine is a dandy once you figure it out.
