Or you could just mount one of your 'Memoria' catts in the bottom bowl-type area........ That's pretty significant, too, right?

It's hard to tell the size on that piece as compared to the size of the orchid you're thinking of mounting, but I think setting toward the center and then letting the outer 'rolls' of the wood frame it might have a more powerful visual impact.

The shape and coloration the inner grain took on is really stunning. Reminds me of flames.

One day... I will try mounting an orchid... And since I'm running out of room very very quickly, I sense the day is coming soon!

All said, it's your memorial artwork and your decision. I still look forward to seeing the finished product.
