Moredhel, I hope the painting of your gran’s urn was a comfort to her family.
Here in Australia a painted biodegradable (cardboard or light wood) coffin is more usual for people who can’t spend a fortune on mahogany caskets and fancy fitments and who want the burial to be less hard on the land.. It can be either buried or cremated. When a friend and colleague died a few years ago I was asked to sing at her funeral, and while I sang both several of her favourite songs and a dirge I had made for her the young people of her family and whoever else needed to do so painted her coffin most beautifully. It was lovely to see, and what she would have wanted. That kind of family sharing can be a huge help in families bearing the loss of a valued family member.
And the lizard is a very nice touch, and suitable to the occasion, being a creature symbolic of regeneration, and of the sun.
