It occurs to me that the effort of making an art card could just as easily be put into a larger work... say, 8.5 by 11, standard letter size. And, that would be almost as easy to ship, to boot. So, I'm going to try a series of these. Here are my sketches so far:
I colored and printed the cat with his paws on the frame already, and he looks good... I'll probably scan tomorrow morning. It's nice to be working at a different scale... gives me more room to paint around on top of the print! I also like how they have the drawn-in bounding rectangle, which the figures overlap on several sides. At this size, I think it's more interesting than the full bleed.
Designs like these would also fit ever-so-nicely on tee shirts. :)
