Eco Printing Leaves on Paper

I spent the afternoon eco-printing Autumn leaves on watercolor paper. So pleased with the results! The method involves pressing the leaves between layers of bundled paper and steaming them in a kettle for several hours. The tannin from the leaves transfers and imprints onto the paper. My plan is to bind these pages into a book. This is one of three batches I made today.   
Art and Nature combined.
