1. Easy Seashell Necklaces

A seashell necklace is one of the simplest and most rewarding beach crafts you can make with kids.
You should start by selecting shells with existing holes or thinner areas that make creating holes easier.
If you need to make holes, you can use a nail or screw with gentle taps from a hammer. Safety precautions should always be followed when using tools with children.
Once you’ve prepared your shells, thread them onto your cord—wax, plastic, or string works well. You can add beads or other decorations between the shells for extra flair.
Remember to measure the length carefully before securing the ends. You can tie them together or add a clasp for a more polished look.
In just minutes, you’ll have created a unique piece of jewellery that captures memories of your beach adventure.
2. Seashell Picture Frame Art

Creating beautiful seashell picture frames lets you showcase your beach treasures and cherished photos in one stunning display.
You’ll want to gather various shells, from large oysters to shimmering Abalone pieces.
Paint some shells in Cranberry or Apricot to add vibrant pops of colour.
Before glueing, lay out your design, placing larger shells in the corners and centre. Fill gaps with smaller shells, creating layers for depth and visual interest.
Once satisfied with the arrangement, secure each shell with plenty of glue. After everything is dry, seal your frame to protect your beach-inspired masterpiece.
3. Ocean Mosaic Masterpieces

Transform your beach treasures into stunning mosaic art with this fun and rewarding project.
You’ll need aluminium pie pans, plaster of Paris, and your collection of shells, sea glass, and marbles to get started.
Mix two parts of plaster powder with one part of water in a large plastic bucket. Then, pour the mixture into your pie tin. Shell art has been used as a decorative expression since ancient Roman times.
You can start arranging your shells once the plaster begins to firm up. It’s helpful to sort them by colour and size in egg cartons beforehand. Press your chosen pieces firmly into the plaster, creating your design.
After the mosaic has completely hardened, please remove it from the tin and smooth any rough edges. To make your shells shine, add a coat of decoupage sealer.
These beautiful creations make perfect decorations for your garden or shelf.
4. Seashell Sorting Adventures

Turn your seashell collection into an exciting learning adventure combining play and educational discovery.
Age-appropriate sorting is an inclusive activity for the whole family, as older and younger children can participate.
Sorting seashells helps develop critical thinking skills while introducing mathematical and scientific concepts naturally and engagingly.
Create an organized learning space with sorting trays or plates, then guide your child through these engaging classification activities:
- Sort shells by size, grouping them into small, medium, and large piles.
- Separate shells by their unique shapes, like fan-shaped, spiral, or conical.
- Organize shells by colour variations, from pure white to rich brown tones.
- Create texture groups, placing smooth shells separately from ridged ones.
Start with simple categories and gradually increase difficulty as your child masters each sorting concept.
You’ll be amazed at how quickly they develop classification skills through this hands-on exploration.
Note: Please only use age-appropriate size of seashells to avoid choking hazards.
5. Colourful Shell Fish Friends

Every young artist will love making vibrant fish friends using their beach-found treasures.
You’ll need shells of various sizes, paint, paper, scissors, and googly eyes to bring these ocean creatures to life.
Start by painting your shells in bright colours, then attach smaller shells as fins to create movement.
Next, cut out a paper fish body and arrange your painted shells to form scales.
You can add sparkle with glitter glue or create unique patterns with different paint colours. The Rainbow Fish book can inspire your colourful shell designs.
Let your children take the creative lead as they design their fish friends. They’ll enjoy selecting shell placement and colour combinations while you supervise using scissors and glue.
Each fish creation becomes a unique masterpiece that captures your child’s imagination and preserves beach memories.
6. Make Your Shell People

Creating charming shell people is a delightful way to bring beach treasures to life. You’ll need basic materials like shells, lolly sticks, string, and decorative items to create these unique characters.
Start by preparing your lolly sticks with washi tape for clothing, then add personality with drawn faces and string hair.
Here’s your step-by-step guide to assembling these beachy friends:
- Cut and shape your lolly sticks to the right size
- Decorate with washi tape for clothes and accessories
- Attach shells using a glue gun for heads or bodies
- Add finishing touches like glitter, buttons, or beads
Don’t forget to experiment with different shell sizes and shapes to create diverse characters.
You can even build a small stage for your shell people and use them as puppets for storytelling adventures.
7. Beach Treasure Hunt

After making shell people, you’ll love taking your kids on an exciting beach treasure hunt.
They should start by creating a list of items they can find, such as seashells, pebbles, and interesting pieces of driftwood.
For younger children, include pictures to help them identify objects, while older kids can use text-based lists. You’ll want to laminate these lists so they’ll survive the beach environment.
Turn the hunt into a learning experience by teaching your children about beach conservation. Remind them to respect wildlife and follow local guidelines about collecting items.
Incorporating photo challenges or working in teams can make it more engaging.
Remember to encourage your kids to pick up litter they spot—it’s a great way to combine fun with environmental stewardship.
8. Shell Math Games

With abundant seashells at your disposal, math games become a natural extension of beach play.
You’ll find that these natural treasures serve as perfect manipulatives for teaching essential math concepts while keeping children engaged and excited about learning.
Try these shell-based math activities that combine fun with fundamental skills:
- Count and match shells to written numbers, strengthening number recognition
- Create patterns using different-sized shells to develop sequential thinking
- Practice addition by combining small piles of shells
- Use shells on a ten-frame grid to visualize basic math concepts
You can modify these activities based on your child’s age and skill level, making math practice feel more like a beach adventure than a lesson.
The tactile nature of shells makes learning concrete and memorable.
9. Ocean Life Learning Display

To bring the ocean’s wonders into your home, transform collected seashells into an engaging educational display that sparks curiosity and learning.
Create a mini-museum by arranging your shells in display cases with labels identifying each specimen’s name and origin.
You’ll want to add a layer of sand to create an authentic beach setting.
Make your display interactive by incorporating educational elements that teach children about marine life.
For example, you can showcase how molluscs build their shells layer by layer using calcium carbonate or explain how hermit crabs reuse empty shells for protection.
Remember to group shells by colour or type and include interesting facts about where they were found.
This hands-on approach helps children develop a deeper appreciation for ocean ecosystems while they learn about marine creatures.
10. Mermaid Shell Accessories

Create magical mermaid-inspired accessories that transform ordinary seashells into dazzling fashion pieces for kids.
You’ll find countless ways to incorporate glittering sequins and beach-inspired designs into headbands, hair clips, and dress-up sets that spark your imagination.
Here’s what you can make with seashells for a perfect mermaid look:
- Shimmering seashell headbands with sparkly sequins
- Easy-to-wear hair clips featuring colourful shell designs
- Custom-made terrarium-style shell accessories
- Complete mermaid dress-up sets with multiple accessories
You’ll find inspiration from online marketplaces like Etsy, where artisans create handmade pieces perfect for everyday wear and special occasions.
These versatile accessories work wonderfully for themed parties, playtime adventures, or simply adding a touch of seaside magic to your child’s wardrobe.
