I used pencils for the skin-tone, and for the grapes - I used my fingers to add the color, using metallic rub ons. For the white highlights, I used Jo Sonja titanium on the tip of my finger..just dabbing here and there. The teeth and highlight of the boy's eye, I used a Sharpie paint pen, in white.
**I'd heard Sharpie was discontinuing these white paint pens - so of course I had to run and buy a box!!LOL
