Card Challenges

So, I went looking for card challenges because I've run across quite a few blogs that mentioned them. I'm so NOT good at setting my own due dates, so I thought maybe trying some challenges might help motivate me to be more creative instead of locking myself into work, work, work (ah, I'm trying...). I'm sure there are many more than I've found, but to the left are links to challenges that I dug up over the last couple of days. If you know of some other fantastic challenges, leave me a comment & I'll check it out!
