Make Galaxy Painted Rocks for an Out of This World Craft

As a nerdy science geek, I’ve always been interested in space and love seeing the galaxy trend grow.  I knew I needed to play around with making galaxies in my crafting, and galaxy painted rocks seemed like the perfect idea.

How to Make a Painted Galaxy Background

Painting a galaxy background is an easy process of paint layering in a combination of black, dark blue, and purple. There’s no wrong placement of the paint, just relax and sponge it in places until you’re happy.

You can always go back and add more black if you’d like your galaxy background a little darker. A super simple spattering technique gives the illusion of faraway stars.

The basic steps I used are below. I started with a black rock, but a black painted base coat works just as well.

What to Add to a Space Painted Rock Background

Once you’ve finished your space rock galaxy background, the sky is the limit! (Pun totally intended!)

Use the galaxy background as a base for a constellation like I did here, add a funky alien, spaceship, planet, or whatever your imagination desires.

Make galaxy painted rocks as part of a space science unit, at camp, or just a fun project at home on a rainy day. They’re intergalactic fun for everyone!
