Here's a unit I recently finished. These wooden flats are from Russia, 45mm to the eyes. They're for my imagi-nations war of ca. 1820: Celtican infantry, le 7eme de Ligne.
The figures start like this. Wooden blanks without detail. Thickness is 4mm at this scale. Definitely a painting challenge as where to place the details is a matter of estimation.
I did a bit of shading but not at the edges. As the thickness means they're almost semi-round when viewed at an angle, edge shading does not work as it does on a conventional flat. And I gave them toy soldier faces from the front.
Next up, cavalry and artillery.
