For this Grinch craft, you will obviously need some rocks! I really like these flat river rocks for painting from Amazon.

It can sometimes be hard to find the perfect flat rock for craft projects and so these rocks make it easy! But if you want to go out rock hunting, just be sure to wash the rocks that you find thoroughly before using them for your project.

Supplies

2-3” oval rocks – Flat rocks are the easiest to work with, but hunting for your own makes it extra fun.
Green acrylic paint – It’s not the Grinch without green.
Black acrylic paint – For sketching in those classic Grinchy features.
Yellow acrylic paint – For the Grinch’s eyes.
Red acrylic paint – A pop of color for the pupils.
Paintbrush – A fine tip works best for details, but any small brush will do.
Pencil – Great for sketching your design before painting.
Mod Podge (optional) – Adds a protective shine if you want to keep your Grinch around for years.

Instructions

Start by downloading the free Grinch printable to use as a guide if needed.

1. Paint the entire rock green and let it dry.

Tip: Use a little putty on the back of the rock to stick it in place while you work.

2. Lightly sketch the Grinch’s features onto the rock with a pencil.

3. Paint on the features (eyes, nose, and mouth) with black paint, then fill in the eyes with yellow.

Tip: A fine tip paintbrush works best for this.

4. Add tiny red pupils to the eyes and allow the paint to dry completely. Seal with a coat of Mod Podge (optional).

Paint multiple rocks at once for easy handmade gifts to share.
Store leftover acrylic paints upside down to keep them from drying out.
Smooth rocks work best, but if yours are rough, give them a quick sand before painting.

Frequently Asked Questions

What kind of paint works best on rocks?
Acrylic paints are the best because they dry quickly, stick well, and provide bright, bold colors.

Do I need to seal painted rocks?
You don’t have to, but sealing with Mod Podge or a clear spray keeps the paint from chipping and makes the design last longer.

Where can I find rocks for painting?
You can buy flat painting rocks on Amazon or look for them outdoors — just make sure to wash and dry them before painting.

Can kids do this craft on their own?
Yes! Kids can easily paint the base colors and use paint pens for details, though you may still want to provide some adult supervision.
