You might expect someone like me (a trained artist, and all that) to get excited about beautifully decorated coffins, but I don't. I suppose that having one standing in the corner of your living room as a memento mori and conversation piece might be interesting, if you have room, but why commission someone to spend hours creating a work of art that will be either buried or cremated with you? Seems such a waste, not to mention a sort of post-mortem showing off.
No thanks. I'd rather that my dearly beloved commissioned something that they like to hang on the wall or stand in the garden, and buy the cheapest environmentally-friendly coffin for my remains. It's only going to keep me tidy in transit.
Paying for an elegant headstone's another matter, if you really want one. At least they'll last.
