Lay skeleton out on sheeting or hang up in the garage or wide workspace area.

Mix 1/4 of brown acrylic paint with water in a cup and stir until blended.

Paint with light strokes over the skeleton with a small paintbrush.

Go over the paint again with a larger paintbrush to spread the paint out. You want it to be a thin coat that you can see some of the bone through. Just like a light whitewash coat.

Paint front, back, and interior of ribs on the skeleton.

Let the paint dry.

Paint the center of the black eyes and nose with black paint. I left some of the original paint showing. My skeleton's eyes and nose were more dark grey so I used the black paint to add depth to the eyes and nose.

Lightly paint white on the teeth to make them pop and that's it!
