Jo Murray shared that an Australian, Joel Lambeth is hosting a collection of collages again this year and is seeking participants. He'll choose 12 participants from the submissions who will then each get sent the same packet of materials from which to make their collages. You can see 2011's results here. It's ONLY cut and paste collage, so if that's your medium, be sure to check out the project here. Deadline is June 30.
Then, Karen at IamRushmore is hosting a postcard swap via Flutterbye. That's a new site I just discovered that's just filled with free tutorials and lots of general art info that is definitely worth a visit. If you've been pining to join a postcard swap, here's your opportunity. Join the Art Swap group and watch for notifications.
Maybe this video of real time calligraphy is more your style.
Hope you enjoy....
