Yellow acrylic paint
Fine detail brush
Medium flat brush
Toothpick or dotting tool
Clear sealant spray
Reference image of constellations

Step-by-Step Instructions

1

Step 1: Create the night sky base

Wash and dry your rock. Paint the entire surface with dark blue or navy paint. While still slightly wet, add touches of black around the edges and blend for a deep space effect. Let it dry completely.

2

Step 2: Add background stars

Using white paint and a toothpick, dot tiny stars randomly across the dark surface. Vary the sizes — some barely visible dots, some slightly larger. This creates the background starfield. Add a few yellow dots for warmer stars.

Step 3: Mark constellation stars

Choose a constellation like the Big Dipper, Orion, or Cassiopeia. Using your reference image, place larger white dots where the main stars of the constellation should be. Make these dots noticeably bigger than the background stars.

4

Step 4: Connect the stars

Using your fine detail brush and white or light blue paint, draw thin lines connecting the constellation stars in the correct pattern. Keep the lines thin and delicate. You can add a subtle glow around each main star with diluted white paint.

Step 5: Label and seal

Optionally, write the constellation name in small letters near the pattern. Once everything is dry, spray with clear sealant. Your constellation rock is a pocket-sized piece of the night sky!

Step 6: Add RoxGeo Code

On the bottom or back of your rock, write ROXGEO.COM followed by a slash and your rock’s unique code (e.g. ROXGEO.COM/ABC123). This lets the finder go directly to your rock’s profile page and log their discovery. If the rock is too small for the full address, write #ROX followed by the code without spaces (e.g. #ROXABC123) — it’s short, easy to search on Google, and leads straight to your rock’s journey page. Use a fine-tip permanent marker or acrylic paint pen, and seal it with clear varnish so the code stays readable through rain, sun, and adventure.

Helpful Tips

Use a flat, dark rock — it already looks like the night sky and needs less paint.
Look up real constellation maps to make your star patterns accurate.
Splatter white paint by flicking a loaded toothbrush for a Milky Way effect.
Try painting different constellations on multiple rocks to create a set.
Glow-in-the-dark paint for the stars makes these rocks magical at night.
For the RoxGeo code on the bottom, use a waterproof permanent marker (like Sharpie) or an acrylic paint pen. Apply 2–3 coats of clear sealant over the code — this keeps it readable through rain, sun, and handling for months.
Writing #ROXCODE (e.g. #ROXABC123) on your rock makes it easy to find via Google search. We actively optimize for this hashtag, so anyone who searches for it will find your rock’s profile page quickly.
The full address ROXGEO.COM/CODE takes the finder directly to your rock’s card, where they can see its full travel history, previous finders, and photos from every stop on its journey.
