Cool idea! I wonder if there's a thin 60mm blank like the 47mm chips.Just thinking out loud here ...
What if it were a two-piece dealer button? The top DB would be colored bright pink with sprinkles. The bottom DB would be a tan cake-color, and the rolling edge could have a wavy pink edge to match the top DB. Then maybe use a hole-saw (or large drill bit) to cut out the middle. Although, I'm not sure the hole is really necessary. It could be just part of the design.
And super-glue the two pieces together, obviously.
Wait! a 47mm thin pink chip on top of a 60mm brown donut chip.
MMMMM.....donuts.
