I made two Doctor Who themed cards for my Australia partner, though only one was required. (I like to send extra ATCs and decorate the envelopes if I have time.) I didn't over do the card hoping that "less is more." I didn't want to cover up the backgrounds, which were made of stained cardstock that I made in 2012. I used the same backgrounds for some Halloween ATC trades in 2012. The color was supposed to be black, but it turned out gray instead. You never know what you are going to get with my paper staining technique. It is always a surprise, usually pleasant, but occasionally a disappointment. I was hoping these backgrounds would suggest the atmosphere surrounding the traveling Tardis. I took these photos with my phone because my scanner is not working, and the digital quality is not very good.
My other trading partner had an alphabetical list of likes. For "Z" she listed zentangles, so I experimented with some zentangles. These may no longer qualify as zentangles, but I like the results of my experimentation. Again the quality is not very good. Scanning gives a much better result.
