Please repost your great question under the community tag as not many Cuties look here, then you will get some great answers. Digitising is a whole new area of machine embroidery. You are about to have hours of fun with your machine and new hobby. Welcome to Cute. When you repost we will remove this posting. PS I use PE8 design softwear which does loads more than monograms.
Welcome to Cute
I am afraid I am not much help. I have not found the time to get into the digitizing aspect of the craft. You will get answers if you post this in the Community section where other members will be checking posts. Q&A is designated to questions about how to navigate the site. I will give you a chance to repost that and will delete this one afterwards.
