I am doing a bust of my dog and I used a projecter to put the image on a very large piece of paper on the wall, then scetched it on the paper. Once that was done I drew it in so there were actual pieces . Then i placed very thin interfacing over it and traced the image on to that. I then cut out the pieces of interfacing and ironed them on the back side of the fabric piece I had selected. I took a class from Janet Fogg on this process. Maybe you can find a web site on her process. Mine is sure coming out nice! good luck.
