At a group I belong to All Things Tim, we do a monthly mailer swap taking one of Tim Holtz technique challenges from 2008 and current month. You can make whatever you want you just have to use the technique from his challenge. I participated in this for the first time in October and just finished my November tag. Please take a look and let me know what you think. Here are the links to the challenges if you want to try them yourself.
