If you sign up for the newsletter every Friday you will get a free file to download. I've downloaded quite a few to use on my Silhouette. I think you can even get it for different file formats.
EDITED TO ADD:
This is from the newsletter directly:
Download files in AI, DXF, GSD, KNK, SVG & WPC plus printable patterns in PDF format. Clean cutting vector files work with Wishblade, Klick-n-kut, Sillouette, Craft Robo & Cricut using SCAL (Sure Cuts A Lot).
