I've had some frustrating experiences with FSL designs I had to convert. They were stitcing out with very small and very dense stitches and causing the thread and sometimes the needle to break. Some even had the underlay stitchs outside the design or not line up. First I tried enlarging the designs (by 15%) in the machine to not change the stitch count. It worked on some designs, but not to my satisfaction with the angels from Bejoscha. Remembering a problem I had when test stitching for Teri, I tested my theory. (I'm getting there:-)
Well, the problem is Digitizer Pro doesn't like PES designs and does a poor job of converting them to JEF. I started over and converted the PES designs in Tajima. They stitched out beautifully.
