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.

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.
