What You’ll Need

Sponges or foam sheets (kitchen sponges work great)
Scissors or a craft knife
Washable or low-VOC interior wall paint
Paper plates or shallow paint trays
Painter’s tape
A drop cloth or old sheet to protect the floor
Chalk or pencil for sketching
Small roller or brush (optional, for background areas)
Optional: hot glue and bottle caps (to make stamp handles)

Step 1 – Design Your Wall Layout Together

A mother and daughter sit on a patterned rug, coloring a sun mural on the wall with yellow crayon, under the handwritten word “dreamscape.” In front of them lies an open sketchbook and a tray of colorful oil pastels, creating a warm and creative bonding moment in a cozy bedroom setting.

Before you grab the paint, sit down with your child and brainstorm. Choose a fun theme that excites them, stars and moons, rainbows, sea creatures, hearts, clouds, or jungle animals. Keep it simple enough to turn into sponge shapes.

Once you have your idea, sketch a rough layout on the wall using chalk or pencil. You can go for a random scatter of shapes, a border around the top of the room, or clustered patterns in one area. Let them help plan, it gives them a sense of ownership and excitement.

Step 2 – Make Your Custom Foam Stamps

Use scissors or a craft knife to cut your chosen shapes from sponges or foam sheets. Keep the shapes chunky and bold, thin or tiny details can blur when stamped. If you want easier grip for little hands, hot glue a bottle cap or wood scrap to the back of each stamp.

Let your child test the stamps on paper first. This gives them a feel for how much paint to use and how to press evenly. It’s also a great way to work out color combos before they go on the wall.

Step 3 – Prep the Wall and Workspace

A blank white wall is sectioned off with blue painter’s tape in a grid pattern, preparing for a mural painting. On the floor are open paint buckets in vibrant colors including blue, yellow, pink, green, orange, and purple, along with paintbrushes and a protective drop cloth.

Clear the space and lay down a drop cloth to protect your floors. If you’re only stamping one section of the wall, use painter’s tape to mark off the area. Wipe down the wall with a dry cloth to remove dust, which helps the paint stick better.

This is also the time to pour your paint onto plates or trays. Stick to a small amount at first, you can always add more, and it keeps cleanup easier.

Step 4 – Dip, Stamp, and Let the Magic Happen

A smiling toddler with paint on her cheeks presses a foam stamp into bright blue paint on a cardboard surface, surrounded by colorful paint cups and brushes. The background shows a wall decorated with vibrant geometric shapes, adding a playful and artistic vibe to the space.

Have your child dip the sponge lightly into the paint. It should be damp, not soaked. Then, let them press it firmly and evenly onto the wall. Encourage them to lift straight up to avoid smearing.

You can layer different colors or stamp types for a more complex mural. If your theme includes stars and planets, for example, you might use gold paint for stars and blue for swirls of comets or galaxies.

Don’t stress about perfection. Slight imperfections make it even more special, and your child will love knowing they did it themselves.

Step 5 – Let It Dry and Touch Up

Let the stamped shapes dry for about an hour. If any areas need a little cleaning up, use a small brush to neaten the edges or fill in paint gaps. You can also paint over any mis-stamps with your base wall color.

If you want the mural to last longer, you can seal it with a clear coat. But if you’re in a rental or just want it to be temporary, skip the sealant so it’s easier to repaint later.

Tips for Success

Use washable or water-based paint for easier cleanup
Test stamp pressure on cardboard or paper first
Keep baby wipes on hand for fast fixes
Work in small sections to stay focused and neat
Limit to one wall or corner to keep the room balanced

Satin or matte wall paint works well. For kids, washable tempera or low-VOC paints are safer and easier to clean.

Can toddlers help with this?

With guidance, yes! Use larger stamps, simple shapes, and only a few colors at a time to keep things manageable.

How do I clean sponge stamps?

Rinse them right after use with warm water and a bit of soap. Let them air dry fully before storing to prevent mildew.

Try rainbows, nature scenes, stars and planets, undersea animals, jungle shapes, or abstract patterns with their favorite colors.
