[Craft] Make and Display! A Special Feature on Ideas for Making Koinobori (Carp Streamers)
When it comes to Children’s Day, many people think of koinobori (carp streamers).
Koinobori are displayed at schools and at home to wish for children’s healthy growth.
This time, we’re sharing ideas for making koinobori.
There are plenty of fun ideas: perfect for wall displays, ones that use handprints and footprints, and even wearable versions! If children arrange them freely with their own ideas, they can create wonderfully unique koinobori full of personality.
Through making activities, let’s also teach the origins and customs of Children’s Day to deepen their interest in the event.
We use the term “seisaku” in the text because the items children create are treated as works or projects.

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.

Wiggly, wriggling carp streamer

When you sway its body from side to side, it looks just like a snake! This is a fun, wiggly carp streamer.
First, cut the construction paper in half and connect the pieces vertically to make it longer.
Fold it accordion-style into four sections to make it long and narrow, then snip slits with scissors to create the scales.
Open the paper and make mountain-and-valley folds between the scales to turn it into a wiggly carp streamer.
Draw eyes on the face area, then trim part of the lower section to form the tail fin.
Add patterns to the scales, and it’s done!
Swim with the wind! Hanging carp streamers

Feel soothed by the way it gently sways in the breeze.
Let’s try making a carp streamer with origami.
First, cut the origami paper into three equal strips so each measures 15 cm by 5 cm.
Take one of the strips, fold it lengthwise into thirds, then make alternating slits from the top and bottom at 0.5 mm intervals.
Leave 3 cm on both the left and right ends, as these will be the face and the tail fin.
Once the slits are made, gently open the paper and carefully spread each woven section one by one.
Attach an eye on the left side you left intact, then cut the right side with scissors to form the tail fin, and you’re done.
If you make a slit in the face and thread a string through it, you can hang it as a decoration.
Craft punches are cute! Easy Koinobori (carp streamers)

Here’s a cute craft idea: attach an origami carp streamer to a base and decorate around it with flowers made using a craft punch.
To make the carp streamer, fold 1 cm along the left edge so the white side faces out, flip it over, and fold it into thirds.
For the tail fin, crease it first, then cut it off in a triangle.
Add scales and an eye to finish.
Once the carp streamer and a pinwheel are attached to a round backing, scatter the craft-punched flowers to make it festive.
Punch a hole at the top, thread a string through, and you can use it as a wall decoration.
Footprint Koinobori
Here’s an idea for making carp streamers using footprints.
First, take the children’s footprints.
Be careful to prevent slipping while there’s paint on the soles of their feet.
Once the footprints are dry, draw the eyes on them.
You can add scale patterns, too.
Attach the footprint carp to a straw or stick to act as a pole.
Painting the bottoms of their feet might feel a little ticklish or be an unfamiliar sensation, and that part will likely be fun as well!
