Kitty, I have found the best file to use is a vector...I have the best luck with .wmf files. I did bring the file into 6D's paint and did minimal clean up.
In in my experience the sales pitch gives you the idea that you can create an embroidery design from a pic in just a few short clicks...... And even though Vikings software has come a long ways.... There are a few steps that make your embroidery design successful.
i am sure there are many people on this site who are experts at this software....but you may pm me and I can share with you what I have learned.
