As I have never done any carving, I have decided to join this Group. I am using a combination of a #11 scalpel blade and a 1.5 mm micro-chisel.
My first step was to glue the blank onto a piece of scrap wood with yellow Elmer's. I clamped it in place for an hour before getting to work and then scraped off most of the laser char. As recommemded, my first task was to make the stop cuts. The key here is to only take off a tiny piece until one is happy with the effect. In addition to the red lines shown in Chuck's sketch, I added stop cuts on various spots of the crown, looking at what Chuck did for guidance. Finally, I have started to smooth down the corners. The last picture was taken to better illustrate the depth of the cuts.
Next, I will make up some 400 grit sanding sticks to improve the surface finish.
