There's a new challenge blog on the web - Scrap Online Challenges. (There's also a SOL group over on Papercraft Planet.) This challenge group hass an interesting twist on your usual challenge. Before the new challenge is issued, a supplies list will be posted (how many pieces of cardstock, how many images, etc.). The sketch (or photos of the project) will be posted a day or so later. Check out the Scrap Online blog or Papercraft Planet group to get a better description of how this works. I've checked out the most recent sketch and it looks pretty fun!
