Stained glass carp streamer
This is an idea for making very cute stained-glass-style koinobori and hanging them from the wall or ceiling.
Cut out the belly section of a koinobori made from colored construction paper and attach transparent cellophane.
Transparent origami is sold at 100-yen shops these days, so that would be great to use too! Layer different colors of cellophane or transparent origami to look like scales and stick them on.
When you hang it up, light will shine through and sparkle, creating a very beautiful koinobori.
Turn mini carp streamers into big carp streamers!
A large koinobori (carp streamer) displayed on the wall.
It’s a common May wall decoration wishing for children’s growth, but if you look closely… the big koinobori is made up of many small koinobori.
Each child makes their own small carp streamer.
They can color it in their favorite hues, or you can unify the colors—warm tones, cool tones, etc.—to create different overall effects.
There are many ways to make them: draw with crayons, create a collage with origami, or use a wet-on-wet bleeding technique.
Enjoy the variations in color as you create them!
Hanging paper-cup koinobori (carp streamer)
Paper cups are a staple for craft projects.
Here’s a wall decoration idea: make koinobori carp streamers using paper cups and hang them up.
Use white paper cups and let each person paint them freely, glue on colored paper, or draw scales—it all works.
For infants, try using stickers to represent the scales and eyes.
Using pre-colored paper cups would also make for a cute and colorful decoration.
Punch holes, thread string through, and connect the koinobori to create a gently swaying hanging display.
A carp streamer made with an origami samurai helmet
Speaking of Children’s Day, a kabuto (samurai helmet) is an essential item, too.
Children’s Day is a day to wish for children’s healthy growth, and the kabuto symbolizes protection from danger and misfortune.
Here’s an idea: let’s make a wall-hanging carp streamer using origami kabuto.
Each folded helmet is small—about the size of your palm—but when you stick a lot of them on, you’ll get a very striking carp streamer.
The kabuto parts pop out a little, making the scales look three-dimensional, which is really cool!
Iris flowers and carp streamers
Children’s Day is also called Tango no Sekku and was originally a festival for boys.
The iris (hanashōbu) became a motif for armor and other martial gear, and it grew common to decorate with irises as the festival flower for boys’ day, Tango.
This idea is to decorate an entire wall with those irises and carp streamers (koinobori).
The refreshing contrast between the koinobori—looking as if they’re swimming against a clear May sky—and the irises in full bloom during the fresh green season makes for a lovely wall display.
How about decorating the wall together with pinwheels and samurai helmets (kabuto) as well?
Koinobori wreath

This is a koi-nobori wreath made from origami.
Its biggest feature is that, although you might imagine a wreath being assembled by stringing decorations together with thread or cord, this design doesn’t use any of that.
You form each piece of origami into a triangle with an insertion slot, and combine six of them in a circle to complete the wreath.
Then attach the koi-nobori in the center to finish the wall decoration.
By changing the colors of the base wreath, you can also adapt it for occasions like Christmas, so give it a try!

Puffy scales! Cute koinobori (carp streamer)

This is a wall decoration of carp streamers that makes you want to touch the plump, three-dimensional scales.
You complete it by attaching origami-made scales to a carp streamer base cut from construction paper.
To achieve a three-dimensional look for the scales, cut them into teardrop shapes, make a slit, then slightly overlap and glue the two sides of the slit.
At this point, the key is to have the lower part of each scale sink in with the colored side concave, and the upper part rise with the colored side convex.
Using traditional Japanese-patterned origami for the upper parts adds a festive touch.
