I can do it for you if you like, but it sounds like your problem is improper stabilizing, and perhaps hooping too loosely. If your fabric can move around, it will get all wonky. Another thing is that sometimes designs can just be crappy, especially free ones. I would suggest hooping your stabilizer, tightly, then spray with your fav spray adhesive, place fabric on top nice & straight, with no wrinkles, and try again. The bad outlines are part of the learning curve of embroidery. It can really wreck a good design.
Also, I downloaded the butterfly design, and in embird, it looks like the outline is off a bit to begin with, so it might just be a bad design
