Sure if you think anyone would be interested. Here is where I am so far.
1. Get some polymer clay. It is not modeling clay which does not harden. I used several brands like FIMO. Bottom left corner it says something like 230 degrees 20 minutes. Must be the hardening stuff. Many colors “Michaels” has it on sale at less than 1/3 runs about $2-7
2. Knead the clay till it is workable. Might try some softener that makes it easier to knead. Rather stiff stuff
3. I got a kit from Amazon that had a roller, knives, and stylus for a few bucks.
4. Push clay into the holes and pack it tight. I found that applying a backer board at this step makes it easier ‘cause the clay oozes out the back and it becomes a push and shove contest.
5. Leave some clay proud of the surface. If you have the sharp knife cut the clay even on the front surface.
6. Bake in an oven or as in my case in my Air Fryer at 230 F for 20 minutes for 1/4 inch thick
7. Sand and finish I have used polyurethane and or lacquer still working that out.
8. Longevity and wearability still in the I don’t know stage.
