i recently purchased a bernina 730 for (i am so proud of this) $15 at a yard sell. but i am trying to use some of the automatic stitch settings but can't seem to get it to do anything other than a straight line. i have the Guide that came with the machine but i have tried using the different settings it suggests but i can only come up with a straight line. i am trying to play around with the machine and figure out what all i can do. is it possible to embroider letters?
