After being intrigued by Judy's lettering transfer method, I did some digging around on the internet and came across this:

It's about using Golden Digital Ground medium for making a wide variety of surfaces suitable for ink-jet printing. I found the idea of printing onto aluminum foil especially interesting (think about Christmas cards).
On the same site there are also some examples of what Judy showed us, using other colors and texture mediums as well.
