Instructions

1. Paint base coat on all rocks using 1/2" paintbrush and white acrylic paint. Use 2-3 coats as needed to cover, and dry completely.
   
   
   
2. Draw blue circle in center of rock top and fill in to make the base color for the iris. Add darker blue layer around outside of iris.
   
   
   
3. Choose a lighter aqua or green for the center of iris, and draw a jagged circle to add gradiation to the eye. Fill in with the same color.
4. Use gel pens to draw thin lines within blue ring to create depth as shown. Leave darkest outer ring untouched. Begin with dark blue and alternate lighter and darker shades over top until you reach desired effect. I like to add one metallic color to provide a little realistic reflection shimmer.
   
   
   
5. Draw black filled circle in center of iris for pupil. When dry add a highlight to the pupil using white paint marker.
   
   
   
6. Use red paint marker to draw branching veins from back of eyeball painted rock toward front. *note* You can also use red gel pens or a tiny detail paintbrush and acrylic paint to make the veins. Using thick lines toward the back of the rock eyeball and thinner lines toward the front will give a more realistic look.
   
   
   
7. After paint is fully dry, apply glossy sealer following manufacturer's instructions to protect paint and add more realism.
