Sparkling hourglass

Let’s make a cute, sparkly hourglass that doubles as interior decor.
Prepare two small bottles, glitter to use as sand, a clear plastic file sheet, and decorative parts.
Cut the clear file slightly larger than the bottle opening and make a hole in the center for the glitter to pass through.
Attach tape and half-cover the hole, then glue it to the bottle.
Add the glitter and glue on the other bottle.
Finish it off cutely with decorative parts.
After adding the glitter, be careful not to turn it over until the adhesive has dried.
Chiikawa mini storage
Get soothed by cute characters! Here are some ideas for Chiikawa mini storage.
“Chiikawa” is short for “something small and cute,” and many fans find comfort in the everyday lives of the characters featured in the anime and manga.
This time, let’s make mini storage items with a Chiikawa motif.
You’ll need cardboard, character pocket tissues, double-sided tape, a craft knife, shatterproof glass film, and some tape.
They’re practical and will make organizing feel exciting!
Shaka-shaka accessory pouch
Just looking at it is soothing! Here are some ideas for a “shaka-shaka” trinket case.
Some kids might want to make their own favorite cute container.
This time, let’s make a shaka-shaka trinket case using materials you can find at a 100-yen shop.
You’ll need a clear round gift box, beads and charms, tape, and washi tape.
Put the beads and charms into the lid of the gift box, then secure it to the bottom part of the container with tape—and you’re done! Adding decorative washi tape to the container itself will make it even more festive.
Minecraft accessories
Let’s make some game character merchandise! Here are ideas for Minecraft-themed accessories.
Minecraft is a globally popular game, and it even had a movie released.
How about making accessories inspired by Minecraft characters this time? You’ll need a grass-like sheet material, wooden cubes, scissors, black felt, strong double-sided tape or glue, an awl, and accessory findings.
You can get all the materials at a 100-yen shop, so feel free to give it a try!
Tabletop clay accessories
Small clay mascots that can sit on a tabletop test your attention to detail precisely because you’re aiming for a compact, easy-to-display size.
While you’re free to create whatever you like, it’s fun to build a unique world with things that don’t exist in reality—like a pig popping out of a flowerpot or a sheep blooming like a flower.
Paying close attention to details such as the pig’s and sheep’s coats to craft them finely adds realism, which in turn makes the finished piece’s strangeness stand out even more.
Using clays in a variety of colors for a colorful finish is a key point that enhances the joy of both the making process and the display.
Made entirely with origami! Triangular accessory case
Make it using only origami! Here’s an idea for a triangular trinket box.
It’s perfect for kids who are good at crafting with origami or for anyone who wants to use the origami paper they have at home to make something.
How about creating a little container to hold small items or parts? All you need to prepare are three sheets of origami paper.
Solid-colored paper works fine, but using your favorite patterns or holographic origami can change the vibe and make it more fun!
Long Boots Piggy Bank
Let’s make use of those memory-filled items! Here’s an idea for a rain boot piggy bank.
Many of us feel that children grow up so fast.
Clothes and shoes need to be replaced each time… throwing them away as they are is such a waste! This time, let’s repurpose outgrown rain boots and turn them into a piggy bank.
What you’ll need: outgrown rain boots, interlocking foam mats, scissors or a utility knife, adhesive, and so on.
It’s nice to be able to keep using your favorite rain boots as a piggy bank, isn’t it?
