Rachel of Average Jane Crafter points us to The Back and Forth Project that just got started up by two crafty ladies, Shannon Lowry and Kathie Sever.
From the site:

We are two friends who are working on a collaborative DIY children’s book called Ruby and Esme. This blog will chronicle our back and forth efforts as we write, illustrate, package, and publish this story. We’d like to build a tribute to the physicality of moving something back and forth between two people — and utilizing the internet as a means to document the beauty of getting back to a more multi sensory, visceral experience of staying connected. We invite YOU to submit a project you and a friend will make and pass back and forth through the mail as you each embellish it.
