In over 12 years as a craft blogger, I've only shared a painted rock craft once. Time for another! Here is a cat painted rock. To clarify, it's not a cat-painted rock. I painted it. I don't even have a cat, let alone one who paints. Affiliate links below.
Cat Painted Rock
Use the white colored pencil to lightly sketch the shape of your cats. I started with what would become the gold cat and worked my way outward. No details - just the oval shape of the cat with ears on top.
Paint the cats whatever color you want. When the paint is dry, add white bellies (if desired) and white eyes (kinda necessary). When that paint is dry, use the Sharpie to outline the cats and add their facial features, including pupils.
Spray the rock with Mod Podge Ultra to seal it.
