how to change size of decorative stitch on Bernina 350
 

Just brought home my new 350 PE! I am sooooo excited! I will take all of the classes that come with the machine, but my schedule isn't open right now, so it will be hunt-and-peck for awhile. I see a stitch that looks like an eyelet (#13). Is there a way to make it larger? I would love to use it for the eyeballs on the robot appliques I am working on! :-) I have succeeded in making it longer, but not wider........any suggestions? :-) Can you tell I am over the moon with this machine purchase???? It is a pretty basic machine, as Bernina's go, but it does all that I want/need it to do, and then some! :-) Thanks for humoring me..................
