I re-stocked a rifle many years ago and planned to do my own checkering. I bought the tools (much too fine I realized later). Made up some scrap pieces of walnut with oil finish and started practicing. After many attempts, I concluded I was not intended to be a checkerer. That took real guts to try it out on your new bow, but obviously, talent is talent. My lack of talent will always remain lack of talent.
You going to try an oval of fine checkering on one of your knife handles next?
I am thoroughly impressed!
