I do stuff like that the Luddite way. I lay out the exact size design on paper. Glue the paper to plywood. Rough cut it out, then send down to the line. Perfect.
If I want more than one, trace the original on wood, rough cut, glue the original to the rough cut. Rout around that, and have a master that I can affix wood to and rout out copies up the wazoo, all perfect copies of the original.

Gather the villagers, pitchforks, torches; we march at dusk!
Some days, the supply of available curse words is insufficient to meet my demands.
.....Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
