Late to the game - but I'm in! Seth of The Altered Page is hosting - Disintegration - artists all over the globe are putting paper bundles (of all kinds) out in nature for several months. Take a beginning photo and then photograph the evidence as time goes on, until the final picture on May 1st - the last day.
Here's my contribution: several old book blocks (the entire book minus the covers) tied together with green and yellow tri-ply string. I used two old books - 100 years plus- and two newer ones - published in the last 20 years. It will be interesting to see the difference of disintegration to the two ages of paper. They sit on a bench in my front garden, underneath a eucalyptus tree waiting to receive the elements. No worry of snow here in Morro Bay, but rain, wind, lots of salt air and eucalyptus detritus.
