I do real well with a 10mm or 12mm in dark row, lightly painted with Petite brand nail polish, color is Island Smoothie, sort of a pearl pink, but just one real light coat, I like to see the dark row thru the pearl brush swirls, and a little black eye made with a sharpie, we clobber them under a float. Just another thought to add to the great info Coley already gave
