Very cool! If you used it for a balmoral, would you leave it square, or have a round outline?

I don't know if there would be copyright issues if you're just doing a one-off for yourself. The moment you sell it and make a profit off it, that's where the potential grey area ends.

At a Ren Faire/Art show I was at, there was a box-maker, with several kinds of boxes with designs wood-burned or carved into the wood. There was one that said "Not all who wander are lost," which was particularly nice. I wanted to get it, but I doubted that the person had permission to use the phrase, so I didn't out of respect for Professor Tolkien.

Cheers,
Nick
