This is one of those "let's try it!" sorts of projects. Incised decorations filled with contrasting powder were used to decorate the Trossingen lyre. I got a softwood (basswood maybe?) box at the craft store and used knives to cut lines into it. Then I rubbed cinnamon into the lines.
Findings:
- The Finnish carving knife worked better than the Xacto knife. The Xacto was too fine, at least for what I was doing (fingerpainting with blades). The lines were so fine they hardly held any cinnamon.
- Hand strength is needed! The knife wants to follow the wood grain, which is probably not where you want it to go.
- I tried sketching some ornaments on with pencil and then cutting overtop. It ended up looking like pencil.
- The cinnamon does highlight the lines, but it's not as dark as it could be. Powdered charcoal is the real thing to use, but you have to use a dust mask with it. Faolan suggested pulverized instant coffee. I had some espresso ground coffee that was old and no longer fit to brew, so I tried to powder it down finer. (Turkish coffee would be fine out of the box.) Haven't used it yet.
I used motifs from the Overhogdal tapestries because they're simple and geometric. I've been up to my ears in Sigurth legends recently, so I picked all the elements that might plausibly be related to that. I did adjust the burning hall motif so that it had men inside instead of women, and added Guthrun standing outside.

That's it, it was just for fun.
