3D scale wall decoration

Let’s make a large carp streamer that’s perfect as a wall decoration! Cut the base of the carp streamer out of construction paper and attach the eye, which you make by layering origami paper.
Next, fold a sheet of origami paper in half twice to make a square, draw a teardrop shape so that the side where the corners are separated becomes narrower, and cut it out.
Make several of these teardrop shapes using both solid-color origami and Japanese-pattern origami.
Snip a slit from the narrow end of the teardrop, leaving a little space uncut at the top.
Layer and glue them so that the solid-color piece dips inward at the center and the patterned piece forms a raised ridge at the center.
Glue the patterned piece on top of the solid-color piece, slightly shifted downward, to complete one scale.
Make lots of these scales and attach them to the carp streamer base, and you’re done!
Tsumami-zaiku

Here’s an idea for making a carp streamer (koinobori) with tsumami-zaiku.
First, cut out the body and face parts of the koinobori from thick paper and attach quilt batting to them.
Next, make the scales using round folds (maru-tsumami), attach them to the body part, then attach the head part and add the eyes to complete the koinobori.
Then, make the iris flower with round folds and create the leaves and the arrow-wheel (yaguruma) with pointed folds (ken-tsumami).
Once all the parts are ready, attach them to the base inside a frame to finish.
For the iris and the yaguruma, it’s recommended to prepare felt on the base and build while sticking the pieces onto it—the shapes will hold more steadily.
Made with a plastic bag

Why not try making a koinobori (carp streamer) using a white plastic bag? First, form the plastic bag into a tube to create the body of the koinobori.
Place it on a desk, draw the koinobori design, and color it in.
Draw the same design on the other side—since the first drawing should show through a bit, you can simply trace over it with a marker.
Make a ring from a cable tie with both ends cut off, thread it through the mouth of the koinobori, fold the plastic bag inward, and secure it with tape.
Finally, punch a hole in the koinobori, thread twine through it, and you’re done! When displaying it outdoors, attach the twine to a main rope using clothespins or a similar method.
mizuhiki (traditional Japanese decorative cord made from washi paper)
How about trying your hand at making a koi-nobori (carp streamer) using mizuhiki cords for good luck? There are several tying methods such as the Awaji knot and the Plum blossom knot, so pick one that seems easy for you or that looks like it will create the shape you want.
By the way, this kind of craft is called “mizuhiki art,” and exhibitions are held around the country.
If you’re looking to start something new, why not give it a try?
Koinobori chopstick rest

Having adorable koi-shaped streamers on the dining table makes the celebration even more festive.
Your child will surely love it, too.
This time, we’re introducing an easy-to-make koi streamer chopstick rest.
All you need is origami paper and a pen.
First, fold the paper in half vertically and horizontally to make crease lines, then fold one side and flip it over.
Fold it into quarters along the center line, fold the corners inward, and use a pen to draw original patterns such as eyes and scales.
Finally, overlap the paper at the mouth side, and you’ll have a three-dimensional, freestanding chopstick rest.
Give it a try!

Let’s make koinobori carp streamers in your favorite colors! Here are some ideas for resist-painting koinobori.
Resist painting with crayons and watercolor is a technique where the paint is repelled by the areas drawn with crayon.
Because crayons contain oil, the paint doesn’t stick to the crayon marks, making the crayon lines and patterns stand out—that’s the key.
Using this method lets you enjoy bright colors and interesting textures, making it a popular technique with children! Try making koinobori that take full advantage of the charm of resist painting!
Koinobori made from clear plastic file folders

When it catches the sunlight, the colors show through beautifully! Here’s an idea for making koi-shaped streamers using clear files.
If you’ve been thinking that creating something with a stained-glass-like transparency is difficult, this is a great idea to try.
You’ll need a clear file, permanent markers, masking tape, scissors, tape, a hole punch, and a straw.
You can also make a samurai helmet out of holographic origami paper and attach it to the tip of the straw for a fun change in vibe.
Give it a try!
wool felt
Here’s an idea for making a carp streamer (koinobori) out of wool felt.
This one is made of wool, but it’s three-dimensional rather than flat.
Prepare wool to match the size of the koinobori, then pull and twist the wool into a roll and felt it by stabbing.
It’s hard to make it at the final size right away, so gradually build it up by wrapping on more wool felt little by little to enlarge it.
Once the base is finished, create the eyes and scale patterns.
You could also use ready-made eye parts sold at 100-yen shops, etc.
Tissue paper carp streamer

Let’s make and play together with kids! Here are some ideas for a tissue-paper carp streamer (koinobori).
Tissue paper is fluffy and light, so it’s great for everyone from infants to adults.
This time, let’s make a koinobori using tissue paper in your favorite colors.
You’ll need a plastic bag, tissue paper, construction or origami paper, printer paper, tape, and a black permanent marker.
First, tear the tissue paper into pieces by hand and put them into the bag.
Next, use construction or origami paper to make the tail fin and streamers, and finish by drawing the scales and facial features with the pen.
It’s done!
Koinobori wreath

Let’s make it with origami! I’d like to share an idea for a carp streamer wreath.
It’s perfect for anyone who wants to make a wreath out of origami or only has origami paper at home.
All you need are origami carp streamers and origami paper.
Create simple parts with easy folds and combine them to complete the wreath.
It’s fun that you can use your favorite color combinations! By adjusting the size of the origami paper, you can also change the size of the wreath.
