plantable papers are my newest favorite exploration in the world of paper. using a heavy weight one in my paper tags for my summer collection so that the paper tags can be composted or planted instead of discarded. tiny sproutlets pop right out of the paper if kept well watered and in the light.
check out san diego based, greenfield paper's other treeless papers too. super neat. hoping to explore more of their earth friendly offerings in collections to come : ) http://www.greenfieldpaper.com/asccustompages/products.asp?categoryid=11
