It's the first time that I've seen one and it was really pretty, somehow more cosy than a wooden one. I think it was quite a bit lighter too as they only needed four to carry the coffin (which is fortunate as my bonkers uncle objected to two of the possible six).
It was, on the whole, a really good funeral. I can't help thinking that Granny would have approved of it even though it was the one thing in her life that she didn't try to have total control over.
