Well, I actually hadn't contemplated making them skins, One was created for 8 1/2" by 11" (as a background for my Creative Resume, so it was faded quite a bit for text to be legible over it), the other for a poster 17" by 22", so the aspect ratio doesn't work as well, but here they are in color, on a background sized approximately for the back of the Kindle.
