Wishful Thinking, my favorite scrapbook and art store, is hosting an Artist Trading Card swap in September (scroll down on the page). The theme is Coffee/Tea Time. The store accepts mail-in participants, so if you'd like to play, shoot them an e-mail at wishful@WishfulThinking-IN.com. The due date is September 15th! Here are a few more specifics.
I won't be playing as September is a busy month and I don't feel up to the level of artistry as those who typically contribute. I need to do a little more practicing first!
Never heard of Artist Trading Cards? According to wikipedia, they are "individual art miniatures that pass hand to hand." Read more here.
