Step-by-step guide to make colorful stamp paintings
Step 1
Lay down a towel or newspaper to protect your table.
Step 2
Place a sheet of paper or cardstock on the protected area for your painting.
Step 3
Squeeze small puddles of different paint colors onto paper plates to make palettes.
Step 4
With an adult's help, cut a potato in half and carve a simple shape into the flat side to make a vegetable stamp.
Step 5
Cut kitchen sponges into fun shapes using scissors to make sponge stamps.
Step 6
Press bottle caps onto paint to coat their bottoms evenly.
Step 7
Gently test each stamp on a scrap piece of paper to check how much paint it has.
Step 8
Start stamping your main design on the paper by pressing stamps firmly and lifting straight up.

Help!?
What can we use instead of a potato for the vegetable stamp if potatoes are hard to find?
If you can't use a potato, substitute a halved apple or a piece of firm craft foam cut and carved like the potato stamp to press into paint.
My stamps are smudging or leaving blobs—how do we fix that?
If your stamp smears or leaves blobs, press excess paint off onto the scrap piece of paper, press the stamp firmly and lift straight up as instructed, and blot the stamp on the paper towel after rinsing it in the cup of water between colors.
How can we change the activity for younger or older kids?
For toddlers, skip the knife and use pre-cut sponge stamps or bottle caps for simple pressing, while older kids can carve detailed potato stamps, mix colors on the paper plate with a spoon, and add brush details before letting the painting dry for at least 30 minutes.
What are some ways to extend or personalize our stamp painting?
Personalize your project by carving initials or shapes into potato stamps or cutting letters from sponges, layering mixed-color stamps and adding paintbrush accents, then let it dry and share a photo on DIY.org.

Facts about painting and printmaking for kids
🪙 Bottle caps (crown corks) are perfect for making small, neat circle stamps — and you can often find them to reuse!
🌈 Mixing two primary paints (red, blue, yellow) can make all sorts of new colors — try mixing on your stamp to surprise yourself!
🥔 Potatoes are a classic kid-friendly stamp because their starchy flesh holds carved shapes really well.
🎨 Printmaking has been used for over 1,000 years to repeat colorful designs on paper and fabric.
🧽 Sponges soak up lots of paint, so sponge stamps make soft, bouncy textures and big patches of color.
