After painting my Middle Earth Quest miniatures, I turned to my Tzolk’in: The Mayan Calendar gears. People have done all sorts of very cool, detailed painting with these, but I was just intending to give them a simple wash to make them look a bit like weathered, stone Mayan calendar dials (like these).
Unfortunately, two coats of the wash spoiled the effect so I just added a little bronzing over the stain and called it a day. (I got the 3d-printed center discs to replace the original stickers from here.) I was most worried about replicating the tiny food day icons/symbols with a painting brush but those turned out great!
