Though traditional postcards are something of an endangered species, truth remains that they are still a great way of saying something nice or funny to someone else. If you use postcards, and think that your designs are good enough to become one, give this site a try: it belongs to a marketing campaign for Hallmark, the renowned greeting card manufacturer, who’s opened their creative department to the work of independent artists, designers and illustrators. By visiting the site, you’ll be able to learn what the tech specs for the cards are, and also view what other people have been sending in. Since the whole idea is that people choose the cards they think are the best, site visitors can rate the ideas they like the best, and the finalists will get their cards added to the Hallmark catalogue and get cash prizes as well. The contests are always themed, and there are a couple of them going on, so that you can get your hands into a variety of topics.
