toy pasta
https://www.tiktok.com/@n.annlee321/video/7336115603255643393Pasta has the image of being an easy, accessible food you can enjoy in many places, and choosing the flavor is part of the fun.
This piece is about using parts that evoke pasta to recreate various variations as mascots.
Since pasta comes in many shapes, let’s carefully plan decorations that match each type of pasta.
It’s important to imagine what ingredients would make it delicious as you create, and to do the detailed work needed to faithfully reproduce those elements.
Corner clip rice balls and sandwiches
Let’s make onigiri rice balls and sandwiches using corner clips for holding papers! For the onigiri, stick double-sided tape on the clip, then attach white, long-pile yarn to it.
Next, glue a small square of black felt on top to act as the seaweed, and it’s done! It’s also fun to tuck pieces of felt that look like fillings into the gap of the clip.
For the sandwich, prepare white felt cut into a triangle like bread, and felt cut into shapes for ham and lettuce.
Stick them together with double-sided tape in the order of fillings, then bread, and you’re finished! You can customize both the onigiri and sandwiches by changing the colors of felt and the types of “fillings” you cut out.
Ghibli food and toys
https://www.tiktok.com/@n.annlee321/video/7473823171523759378Studio Ghibli’s works are captivating not only for their profound storytelling but also for their meticulous visual expression—especially the way food is depicted so enticingly.
This piece is about recreating the look of the foods that appear in Ghibli films and making beautiful mascots using simple materials.
You’ll experiment with details, like kneading adhesive into shape and using paint to create gradients for a realistic finish.
Since achieving a food-like appearance hinges on material choices, it’s crucial to be particular from the very stage of selecting your materials.
Krispy Kreme-style decorated doughnuts

Krispy Kreme Doughnuts drew attention not only for their taste but also for their colorful appearance.
Focusing on that cute, colorful look, this is about recreating them as mascots.
The base is made by shaping clay in a mold, then adding other colored clays and decorations to embellish it.
It looks fun not only to recreate actual products but also to decorate them in your own way and make original donuts.

A wooden stick works perfectly for the ice pop handle.

Cute lantern made with disposable chopsticks
https://www.tiktok.com/@mami_toys/video/7141827992879172866Let me introduce a cute lantern you can make with disposable chopsticks—fun to display and enjoy.
Prepare chopsticks, glue, and washi paper.
Cut the chopsticks and build the lantern’s frame.
The key is to keep an eye on the balance so the frame doesn’t shift out of place.
Attach washi paper from the back to create the lantern’s window sections.
Finally, glue the frames together to finish.
It’s also recommended to use your favorite colors for the window sections.
The light that leaks through the gaps between the chopsticks looks absolutely beautiful.
