Richard Fudge has begun sending around two prayer journal sketchbooks for artists to make a spread of prayer-infused art and then mail on to the next artist.  The project, which he's calling 'To Send a Prayer' can be followed on its own blog - http://2sendaprayer.blogspot.com/.  I believe I'm right in thinking that he's happy to get more people involved so contact Richard through his blog (http://fudge-art.blogspot.com/)if you want to participate.  I'm going to.

The project was inspired by another mail/sketchbook project called 'Look at Book' which turned out fantastically though it was not about prayer like this one is.
