You're very kind. All of the credit goes to Anthony Herrera (http://www.anthonyherreradesigns.com/starwarssnowflakes) for his amazing creations! I just converted them to be printed.
As for converting these particular ones to CDR, I've already included the SVG files for each item. There's lots of free tools online to convert those to other formats (like CDR); in fact, I'm betting that CorelDraw can import an SVG just fine.
