For proof-of-concept all you need is a lump of softwood.
Yesterday I cut out the face mould and put it on the blank.
In the wrong orientation as I now realise.
I realised that I needed the easing in place and so I measured the slope at the end of the easing where it will join the wreath (50 degrees or so) and made a temporary block to represent the easing end thus..
Marked up the two bevels on the wreath ends (incorrectly as well but we live and learn) and made a support so I could rest the wreath on the easing end and at the right twist so..
That's when I realised that it turned in the wrong direction. Hey ho...let's press on, I thought. The end face on the other end of the wreath should continue on at an angle of 29 degrees. It does. But the bevels aren't vertical. That's when I went indoors for the day and got stuck into several bottles of beer to drown my sorrows.
But I shall persevere.
Now got the face mould the right way (mind you, I still don't understand why I've got to flip it but there you go.). Will shortly be going out and redoing the end bevels and offering it up again. If it's wrong, well, I do have some thick Kingspan !
If opportunity doesn't knock, build a door.
