Endless possibilities! I bookmarked Flickr MiniCards ages ago when the promotion was in full effect and let it fall by the wayside. Now I've been reminded by Swissmiss and can't wait to order my own Moo cards.
Check out the Moo Minicards slideshow to see what others are doing with their Moo Minicards.
My intial ideas:
Eames-like House of Cards
Recipe Cards—easy to share
Portfolio promotional tool (put a few on keyrings)
Share your ideas in the comments section!
Thanks to Swissmiss for reminding me about this with her post!—aaron
