Doing the yard sale thing Friday and open a case to see this. She wanted $3.00 for it and said it worked. Well, ok if it doesn't work hubby said he could play with taking it apart for $3.00. Well he does not get to take it apart!!! It sews a really nice straight stitch. Would like to know if anyone can help me understand the "Darn Knob" at the bottom? Would anyone have a manual or know anything about this. It is a Pacesetter XL700. I have googled and am not having any luck. Help appreciated!
