A box for doing hair styling
@n.annlee321 Perfect for practicing ribbon bows, braids, and using hair ties 🥰🎀#HandmadeToys#100-yen-shop#100-yen shop DIYParentingChildcareChildcareEducational#EducationalToysbraidRibbon bow

Why not make a hairstyling box using a large empty box, felt, and yarn? It’s a great craft for kids who love tying or braiding doll hair.
First, cut out parts like the face, eyes, and mouth from felt, and stick them onto the box lid.
As if making a pom-pom, wrap yarn around cardboard, tie it at one point, then cut the looped ends.
Punch holes in the top of the face area on the box, thread the tied yarn through, and attach the “hair” around the face.
Make the side sections and bangs separately.
Also, secure the side hair at the upper left and right sides of the face.
Finally, decorate as you like with ribbons and more, and you’re done! Use the yarn as hair and enjoy styling it.
Handmade croissant craft
@n.annlee321 Pretty hard to do in real life, huh? 🥹#ElementarySchoolMomSummer Vacation CraftParentingChildcareHandmade#100-yen shop DIY#100-yen-shop

Croissants, whose toasty aroma practically comes through just by looking at them, are a popular bread across generations.
Let’s recreate that delicious croissant appearance using materials you can get at a 100-yen shop.
For the base, cut a puzzle mat into three different sizes, then glue them together while creating steps.
Once the base is complete, apply double-sided tape across the entire surface and wrap brown yarn around it to mimic the look of a croissant.
Since the layered dough and variations in browning are part of a croissant’s appeal, experiment with how you wrap the yarn and also use paint to reproduce these details effectively.
Aroma Fragrance

If you’re looking for an easy, summery craft, I recommend making an aroma fragrance jar! Prepare a jar, gel ice packs, blue food coloring, essential oils, and decorations like marbles or seashells.
First, fill the jar about one-third full with the gel from the ice packs and add the food coloring to tint it.
Once the color is set, add more gel and a few drops of your favorite essential oil.
Finally, add the decorations and put the lid on—you’re done! Using blue food coloring with marbles or seashells makes it look like you’ve captured the sea inside the jar.
Try creating one with your favorite theme!
dollhouse

If she loves dolls, why not try making a dollhouse? In this idea, colored boards and photo frames are used to create walls and windows.
Using pins for furniture legs and buttons for handles, you can build a surprisingly charming dollhouse with just items from a 100-yen shop or things you already have at home.
These days, many miniature furnishings are sold at 100-yen shops, so you can also modify and use those.
Go ahead and create your ideal room.
Handmade toy from an empty snack box

Make it with an empty snack box! Here’s how to create a pom‑pom shooting game! First, prepare an empty box that once held something like Choco Pie.
Reinforce the back by attaching a wooden stick so the lid can stay open.
Next, glue wooden sticks to the top and bottom of a wooden clip and wrap a rubber band around it.
Attach a plastic bottle cap to one end, and fix the other end to the back of the box.
Finally, stick a few small paper cups inside the box wherever you like, and you’re done.
Set a cotton ball in the bottle cap and launch it with a pop—have fun playing!
Original watch

Why not try making a one-of-a-kind original clock using a DIY clock kit? First, draw diagonal lines on a canvas board and drill a hole where the lines intersect to attach the movement.
Sketch a few ideas, then paint your design with acrylic gouache based on those sketches.
To make the numbers stand out, you can create them with paper clay.
If you prepare a template that divides a circle into 12 equal parts, it will be easier to decide the placement of the numbers.
Once you finish painting, attach the movement through the hole you prepared in advance.

scratch art

Scratch art is an art form where you scrape a black scratch surface with a pointed pen or similar tool to reveal colorful patterns and designs underneath.
One of its charms is how easy it is to enjoy.
Let’s try making scratch art by hand.
First, color a clear plastic file folder with bright colors using permanent markers.
Next, paint over it entirely with black paint.
Once the paint is completely dry, it’s ready.
Use a bamboo skewer to scratch the dried paint and draw any pictures you like!
