There’s something about the ocean that pulls little ones in close. All that mystery, all those strange and wonderful creatures, all that deep blue. And the lovely thing is, you don’t need a beach trip to bring it home — just a few paper plates, some paint, and a slow afternoon.
So I gathered 20 of the simplest ocean crafts for kids — the kind that actually turn out cute, made mostly from things you already have tucked in a drawer. Pull this list out on a rainy morning and let those tiny humans make a whole little sea of their own.
why ocean crafts are worth a slow afternoon
Sea creatures are some of the most beloved little friends a child can make, right alongside all the other easy animal crafts for kids that fill our craft basket. There’s a wonder in the deep blue that even the wiggliest toddler seems to feel.
We talk about where each creature lives and how God filled the whole sea with good things, and somehow a paint-spattered afternoon turns into a quiet little lesson in wonder.
“The sea is his, and he made it: and his hands formed the dry land.” — Psalm 95:5
what you’ll need for these ocean crafts
The beautiful thing about ocean crafts is how little they ask of you. Most of what you need is already waiting in a drawer or in the recycling bin. Here’s what we keep on hand:
- Paper plates (the thin, cheap ones work best)
- Washable, non-toxic paint in ocean blues, greens, and brights
- Construction paper and a little foil or shiny paper for scales
- White glue, googly eyes, and a handful of pipe cleaners
- Egg cartons, cardboard tubes, bottle caps, and small boxes from the bin
- Yarn scraps, a clean sponge, and child-safe scissors
I keep these basics in a little basket near the table so we can start without any big setup. Quick access is the difference between a craft that actually happens and one that stays a nice idea.
20 simple ocean crafts for kids
Each one uses basic supplies and forgiving steps. Start with whichever creature catches your little one’s eye and follow the joy from there.
1. Ocean in a Bottle
Fill a clear bottle with water, a drop of blue coloring, and a little oil, then add tiny shells or a pinch of glitter and seal the lid tight. Give it a gentle tip and the whole little sea rolls and settles — calming to watch and a favorite for small hands.
2. Paper Plate Fish
Paint a paper plate a bright color, then cut a wedge for the mouth and use that same wedge as the tail. Add a big googly eye and a few paper scales, and you’ve a cheerful fish in minutes.
3. Rainbow Fish Craft
Cut a simple fish from cardstock and cover it in shimmering scales snipped from foil or metallic paper. Let little ones overlap the scales like shingles for that storybook sparkle.
4. Paper Plate Shark
Fold a gray paper plate into a snapping mouth, then add a triangle fin and a row of pointy paper teeth. Sharks are always a hit with the braver little crafters.
5. Handprint Octopus
Press a painted hand onto paper with the fingers fanned out as eight wiggly legs, then add a round head and a sweet face above. It doubles as a keepsake of just how small those hands are right now.
6. Jellyfish Yarn Craft
Glue lengths of yarn beneath a painted paper dome for long, trailing tentacles that sway with the slightest breeze. It’s a lovely way to use up the odds and ends from your basket of yarn scraps.
7. Salt Dough Starfish
Shape simple stars from homemade salt dough, press in a little texture, and let them dry hard before painting. They feel like real treasures gathered from the shore, and they sit so prettily on a windowsill.
8. Egg Carton Sea Turtle
Cut a single cup from an egg carton for the domed shell, paint it green, and add a paper head, four flippers, and a tail. One of the sweetest uses for something that was headed to the bin.
9. CD / DVD Shiny Fish
Turn a scratched old CD into a glimmering fish with a paper tail, a fin, and one big eye. The shiny surface catches the light just like scales underwater.
10. Milk Carton Aquarium
Cut a window in a clean milk carton, paint the inside a deep blue, and hang tiny paper fish on thread so they float inside. A whole little tank that fits right on the windowsill.
11. Egg Carton Crab
Paint an egg carton cup bright red, add two googly eyes on top, and pinch on a pair of paper claws. A few bent legs finish him off — and you’ll find dozens more ways to use them in these bright and playful pipe cleaner crafts.
12. Paper Plate Pufferfish
Paint a round paper plate a cheerful color and poke paper spikes out all around the edge, then add a surprised little face. Puffy, prickly, and full of personality.
13. Bottle Cap Sea Creatures
Save up bottle caps and turn each one into a tiny fish, crab, or turtle with a dot of paint and a googly eye. They’re wonderful for little fingers and make a sweet sorting game all on their own.
14. Cardboard Seahorse
Cut a seahorse shape from cardboard and let little ones decorate it however they please. A few spare buttons from the jar make wonderful glossy scales, and the curling tail is half the fun.
15. TP Roll Submarine
Paint a cardboard tube bright yellow, then add a paper periscope and a few round porthole windows. Ready to dive to the very bottom of the bathtub sea.
16. Under the Sea Diorama
Line a shoebox with blue paper and fill it with hanging fish, a sandy paper bottom, and a few strands of seaweed. This is the kind of bigger project that fills a whole slow Saturday.
17. Paper Plate Mermaid
Half a paper plate becomes a shimmering tail; add a little mermaid up top with yarn for hair. A favorite with the dreamers in the house.
18. Egg Carton Goldfish
Another humble egg carton cup, painted orange with a flowing paper tail and two little fins. Simple enough for even the very youngest crafters at the table.
19. Mermaid Paper Bag Puppet
A plain paper lunch bag becomes a mermaid puppet with yarn hair, a paper tail flap, and a friendly face. Slip a hand inside and she’s ready to put on a little show.
20. Sponge Painted Fish
Dip a small sponge in paint and dab fish shapes across a page, then add eyes and a few rising bubbles. The dabbing is half the joy for the tiniest hands.
easy tips for a calm ocean craft afternoon
Craft time with little ones doesn’t have to be perfect — and honestly, it shouldn’t be. A few small things make our afternoons gentler:
- Set up before you call them in. Lay out the plates, pour paint into a muffin tin, set out the eyes and glue.
- Let them lead. Show one example, then step back. Their version is always better, because it’s theirs.
- Embrace the mess. An old tablecloth, paint clothes, and zero expectations for a tidy table.
- Don’t rush the drying. Set the finished sea creatures somewhere safe to dry fully before little hands want to play.
turning your ocean crafts into a whole under-the-sea day
Once the creatures are made, they have a way of inviting more play. We tape paper fish to the wall for an undersea reading nook, or float the bottle-cap critters in a baking dish of water for a little ocean of their own.
When the weather is kind, we take the whole basket out to the porch to dry in the sun. If you’re dreaming of real sand and waves, these easy beach crafts for kids pair beautifully with a seaside trip — just don’t forget your homemade tallow sunscreen before you head out the door.
And for the long, golden stretch of summer when the littles need something to do, this list of simple summer activities for kids keeps a craft afternoon company beautifully.
pick one ocean craft and make it today
Sweet friend, don’t try to make all 20. Just pick the one that caught your eye first — the handprint octopus, the rainbow fish, the little egg carton turtle — and see where the afternoon takes you.
There’s no wrong way to do this, and there’s no such thing as a failed ocean craft when a child made it with their own two hands.
When you make one (or five), come back and tell me which sea creature your little ones fell in love with. Drop it in the comments below — I’d so love to hear from you.
Warmly,
Betty

frequently asked questions
what age are these ocean crafts good for?
These work beautifully for children as young as 18 months with a little help, and they stay engaging well into the elementary years. Toddlers can manage painting, gluing, and sponge-dabbing with a guiding hand nearby, while older children can take on the more detailed builds like the milk carton aquarium or the under the sea diorama. The same craft can be simple or fancy depending on who’s sitting at the table.
what supplies do I need for ocean crafts?
Very little, and most of it you likely already have. Paper plates, washable paint, construction paper, glue, and googly eyes cover nearly every craft on this list. Save your egg cartons, cardboard tubes, and bottle caps too — they do a lot of the heavy lifting, and a small basket of these basics near the table is all you really need to get started.
which ocean crafts are best for toddlers?
The simplest ones with big, forgiving steps are best for the youngest hands. The handprint octopus, sponge painted fish, ocean in a bottle, and egg carton goldfish are all wonderful for toddlers. Lean into the parts they love — pressing, dabbing, gluing — and let go of any expectation that it will look like the example. For a toddler, the doing is the whole joy.
do I need special paint for these crafts?
For little ones, I always reach for washable, non-toxic paint. It’s gentle on small hands, comes off skin and surfaces easily, and is widely available. If you’re working with a child who still tends to put things in their mouth, keep a close eye until everything is fully dry. A non-toxic craft space is a small and simple part of a non-toxic home.
can these ocean crafts be used for sunday school or homeschool?
Absolutely — many of these slip right into a lesson. A table full of sea creatures pairs beautifully with the creation story in Genesis, the great fish in the story of Jonah, or any lesson on the wonder of all God made. Because the materials cost almost nothing, they’re a blessing for a classroom or ministry budget, and a sweet way for little hands to connect a story to something they made themselves.
