Rock Painting with Sponges: The Theory

If you’re as obsessed as I am with video learning, you’ve likely gone down the rabbit hole of YouTube’s painting videos.

I go to YouTube to learn how to repair a piece of tile I broke (oops) and end up 4 hours later wanting to make a raised garden bed. #truestory

During one of these YouTube black hole time-sucks, I came across a technique called one-stroke painting. This isn’t the first time I had come across this technique, but after watching 4 or 5 of these videos, I had the idea to try it with my daughter.

SPOILER ALERT: it failed. It failed miserably. 

Sponge Rock Painting for Kids

I won’t ruin the surprise for you but basically, one-stroke painting is the loading of a brush with multiple colors and well, using only one stroke to create an object. It worked for me but as I said, failed with my 6-year-old in fantastic fashion.

Because she felt poorly about it, I wanted her to have a win and came up with this sponge painting idea for her. It’s ridiculously simple and she had a BLAST.

She did this for more than an hour! This one is her favorite because she thinks it makes a good addition to her camping story stones.

Any acrylic paint will do for this project (shown in the video), however, you will have more control over your design with paint pens. See the section below on painting with paint pens and this method.

As far as sponges, we tried two: a kitchen sponge and a makeup application sponge. Both are very inexpensive and don’t have a lot of holes, so they both worked well.

We found more control with the makeup sponges, so for more intricate designs use those.

One-stroke sponge rock painting is such a fun rock painting idea for kids and adults. Using this painted stone technique allows for color variation and unique painted pebble ideas.

Active Time 15 minutes
Total Time 15 minutes
Difficulty Easy


  • Acrylic paint or paint pens (these are our favorite paint pens)
  • rock, painted or natural


  • Sponge (kitchen sponges with small holes or these sponges, which worked best)
  • Paintbrush (if you need to blend colors)
  • Rock (base-coated or natural)


  1. Cut the sponge to fit the rock section you wish to paint.
  2. Apply paint to the sponge directly in a pattern. We tried various patterns, like watercolor splotch, stripes, rainbow, and targets.
  3. Position the sponge and press into the rock. Lift and repeat, if desired. If you're working with young children, mention to them to keep their hands still to make the pattern appear.
