I’ve always loved things that glow in the dark, and I’ve made tons of monster crafts, so combining those two things seemed like a fun thing to do! Halloween is coming quickly and it’s always been my favorite holiday. So making some glow in the dark monster rocks ended up being a really fun way to celebrate, just like making these Skull rocks, too! This post is sponsored by I Love to Create.

These glowing monster rocks are super cute and they are really fun to make. This is more of a weekend project due to drying time, so be sure to plan accordingly.

Making Glow in the Dark Monster Rocks

I used Tulip Glow in the Dark dimensional fabric paint over the top of acrylic paint on my monster rocks. You can use any acrylic craft paint that you want, but I have included the colors I chose below if you want to match them. UV lights and black lights are the best way to charge your glow in the dark paint. Otherwise sunlight is the best since there’s plenty of UV rays there!

Supplies you will need:

• Rocks – you can get these at craft supply stores or here on Amazon
• Tulip Glow in the Dark dimensional fabric paint
• Paint brush
• Black marker
• Black fine point pen or marker

Acrylic paint in colors of your choice (I used Americana acrylics in the following colors:

• Saffron Yellow
• Salem Blue
• Lavender
• Sour Apple
• Red Alert
• Bright Orange

Using colorful acrylic paint means that your glow in the dark monster rocks will look fun even in the daytime! So let’s get started, shall we?

How to make your monster rocks

First off, if you are using rocks you found outside, be sure they have been washed and dried and are completely free of dirt.

This first step is actually optional. My rocks were very dark, almost black. So I chose to give them a couple coats of white paint first. You don’t have to do this, but if you don’t you may end up adding more color coats to cover the dark rocks.

Paint each rock in desired color. Let them dry then add a second coat. Let them dry completely.

Use the “natural” (this is the color name on the bottle) glow in the dark paint to add eyes and teeth.

You will need to prop up your rocks on something that will keep the glow in the dark paint from dripping before it dries. Just make sure the surface is level with the horizon.

At this point you can begin adding designs with the different colors of glow in the dark paint. Try polka dots, stripes and squiggly lines. Be careful not to bump the wet paint with your hand as you design.

PRO TIP: If you make a mistake you can carefully wipe it off with a Q-tip and start again. 

Here’s the hard part, you will need to let these dry overnight. It may even take longer depending on the thickness of your application. Once the glow in the dark paint is dry enough that it has a solid surface, use a black marker to add the eyeballs. You can also use a fine point marker (I use these micron pens for my craft projects) to draw carefully along the edges of the glow paint mouths so that the rocks look good in the daytime as well.

Finally, charge your glow in the dark paint using a UV light or black light. Then turn out the lights to see your cool glow in the dark monster rocks!

If you enjoyed this project, you’ll love these glowing jack o lantern jars made with glow sticks! We also have this glow in the dark Frankenstein jug that’s lots of fun for Halloween. if you’re having a Halloween party or a monster themed birthday party, you’ll definitely want to make these twirling paper monsters.
