Step 1
Clear a flat workspace and lay out all your materials so everything is easy to reach.
Step 2
Look at simple shapes and choose one design like a star heart circle or leaf.
Step 3
Draw your chosen shape on the craft foam with the pencil.
Step 4
Cut out the foam shape carefully with scissors following your pencil line.
Step 5
Check the foam shape against the top of the bottle cap and center it so it fits well.
Step 6
Attach the foam shape to the bottle cap using a small piece of double-sided tape or a dab of craft glue and press to stick.
Step 7
Squeeze a little washable paint onto the plate and use the paintbrush or cotton swab to paint a thin even layer on the foam stamp.
Step 8
Press the painted foam stamp straight down onto the paper and lift up to make one print.
Step 9
Repeat painting the foam and stamping to create a pattern across the paper.
Step 10
Wipe the paint off the stamp and tools and let your stamped artwork dry completely.
Step 11
Take a photo of your finished stamped pattern and share your creation on DIY.org

What can I use if I don't have craft foam or a bottle cap?
If you don't have craft foam or a bottle cap, substitute a kitchen sponge or thick cardboard for the foam and a jar lid or a sturdy piece of cardboard as the cap base, attaching it with double-sided tape or a dab of craft glue as in step 5.
My stamp keeps coming off the bottle cap or the prints look smudged — how do I fix that?
Make sure the foam shape is centered and pressed firmly onto the bottle cap with a fresh piece of double-sided tape or a dab of craft glue (press and let dry) and apply a thin, even layer of washable paint with the paintbrush or cotton swab as described in step 6 to avoid smudging.
How can I adapt this activity for different age groups?
For toddlers, have an adult pre-draw and pre-cut simple shapes and let them press pre-painted stamps, while older kids can draw more detailed shapes on the craft foam (step 3), carefully cut them out (step 4), and design repeating patterns across the paper (step 7).
How can we make the stamped artwork more creative or personal?
Layer colors by letting each stamped layer dry completely before stamping again, combine different bottle-cap sizes and foam shapes to make larger motifs, add glitter or metallic paint before the final drying step, and then photograph your finished pattern to share on DIY.org as suggested.

Facts about stamping and printmaking for kids
✂️ Ethylene-vinyl acetate (EVA) foam is the soft craft foam kids use — it’s easy and safe to cut for stamps.
⭐ Start with simple shapes (dots, lines, stars) — they’re the easiest to cut and make bold, repeatable prints.
🥤 Bottle caps come in metal and plastic and make great little stamp handles when glued to foam shapes.
🧼 Many poster and washable paints are water-based, so they rinse out of clothes and skin with soap and warm water.
🎨 Printmaking lets you make lots of copies from one design — one stamp can create dozens of patterns fast!
