One of my dear friends chose a natural burial, and had a year to prepare. He bought his reinforced cardboard coffin, kept it in the garage for 6 months, and then decided to paint it with scenes of his life. A friend who was an artist joined in, so too eventually his neighbours, (who he did not know very well up to that point) and friends also added their artwork. It seemed to create a ‘melting’ in people, and a joy to do this. He was buried in this with the various artworks and messages painted on it.
