take pic you have, scan it.......save bitmap. take in to corel/ill and blow it up to fit on a std paper sheet, print it.
now take a sheet of tracing paper, tape it to printed one.
SHARPIE NEW one.....do not push down on it let it lay the line you just move it. now after you have it traced..with NO CROSSED LINES or INTERSECTING lines, it ready to be scaned/vectored.......i used STREAMLINE 4.0 and it does great.....might be whats inside CS2 since stremline is adobe. now once you convert save it as AI/EPS. now take into corel/ills and give it a HAIRLINE, AND THEN REMOVE ANY FILL COLOR....now you got a vector image that you can breakapart.....and manipulate all the lines....so you can make a cutable object...
