This is a craft project where you use everyday materials like paper cups, paper napkins, and water balloons to make small, play-kitchen-style items.

The book features recipe-style crafts focused on cute sweets such as ice cream, cupcakes, and pudding, making it feel as fun as flipping through a cookbook.

One especially noteworthy method is making a dome-shaped cup by pasting paper napkins onto a water balloon, letting it dry, and then popping the balloon.

Add toppings made from felt or origami to finish it off so it looks like a real dessert.

You can also customize paper plates and drink cups to create displays that look like a charming little shop.

It’s a visually delightful craft that sparks creativity.

smart ball

[Summer Vacation Craft] A “Smart Ball” you can make with 100-yen shop items—perfect for your child’s summer homework or independent research project!

Smart Ball is a playful craft that lets you build your very own game while getting excited about the motion of a rolling marble.

Cut lumber to fit a perforated board to create a frame.

Add an incline beneath the board so the marble rolls more easily.

For the launcher, use nails and rubber bands to make a pull-and-release mechanism that shoots the marble.

Attach a plastic sheet on top of the board to enhance the sound and feel as the marble rolls.

Place small pegs called dowels to add unpredictability to the marble’s path.

With creative targets and decorations, you’ll have a one-of-a-kind original Smart Ball game.

It’s a fun way to nurture creativity and observation skills as you play.

Marble Maze

Marble Maze

Let me introduce a marble maze that’s so much fun to roll around.

Get your materials ready: a plastic board, colored construction paper, colored pencils, a ruler, a cutting mat, scissors, double-sided tape, clear tape, a ballpoint pen, and marbles.

Cut the plastic board to create the base shape of the maze.

It’s best to assemble the base by attaching pieces around the edges.

For the maze course, cut the board and adjust the sizes as you build.

Create traps by cutting construction paper and attaching them along the course.

Adding tunnels will make it even more exciting.

Roll your marble and enjoy aiming for the goal!

Matchstick crafting play

Art project idea for 3rd and 4th grade elementary students: “Matchstick Art”
Matchstick crafting play

Crafting with matchsticks—creating any shape you like—is a fun hands-on activity that nurtures creativity and fine motor skills.

From arrows and railroad tracks to burst-like patterns reminiscent of fireworks, you can freely assemble designs from flat compositions to three-dimensional forms.

You can arrange matchsticks to draw patterns like a picture, or angle them to build a 3D tower—the key is that each piece emerges from your own unique ideas.

The materials are light and easy to handle, allowing delicate expression even with small combinations of parts.

Displaying the finished pieces side by side reveals a miniature world and sparks the imagination.

With new discoveries each time you make something and the creator’s individuality shining through, matchstick crafts are an idea you can enjoy again and again.

Matryoshka

Matryoshka

The craft of painting your own face and those of your family onto a matryoshka doll—where new companions appear one after another inside a small doll—overflows with the joy and warmth of imagination.

Start by applying a base color with acrylic paint to the surface of the wooden nesting dolls.

Once it’s dry, carefully paint expressive characters such as your self-portrait, family, or friends.

After the paint dries, add a coat of varnish to give it a sheen and significantly elevate the finish.

Each time you open it, a new face appears, making it a delight for viewers.

It also makes a perfect gift, and the key is to create it while thinking of someone special.

It’s a lovely art project that lets you feel the connection between craftsmanship and the heart.

Transformable miniature house

For a summer vacation craft! How to make a miniature house that can be freely transformed
Transformable miniature house

Let me introduce a cute, transformable miniature house.

Using cardboard, choose the coverings for the ceiling, floor, and walls as you build each room.

The key is to keep in mind the kind of room you want to create while you work.

Try stacking rooms or changing the combinations to make a miniature house that’s uniquely yours.

By making the wall coverings with colored paper or using patterned paper for the miniature house, you can add originality and have even more fun.

Cardboard guitar that makes sound

Let's Make a Sound-Making Guitar! [Cardboard Craft]
Cardboard guitar that makes sound

Let’s introduce a fun-to-make cardboard guitar.

Prepare one cardboard box, five rubber bands, a food tray, packing tape, glue, scissors, and a cutting mat, then let’s get started.

Draw a rough outline of a guitar on the opened cardboard and cut out each part along the lines.

Make slits along the long side of the food tray; the depth of the slits will change the sound it produces.

Thread the rubber bands through the slit area.

Attach the food tray to the hole in the guitar body part using packing tape.

Glue the neck and head together.

Then glue the neck and head onto the guitar body to complete it.

Paint it and add decorations to finish your own original guitar!
