Birthday decorations / surprise decoration (11–20)
Pom-pom flower

How about “pom-pom flowers,” hanging decorations for a birthday? All you need are tissue paper in your favorite colors, scissors, and clear fishing line to hang them.
Stack seven sheets of tissue paper and fold them in an accordion.
Next, make two pieces by folding the strip in half at the center, then cut both ends into points so the flower looks neat.
Finally, bundle the two pieces together, tie them with the fishing line, and gently fan out the accordion layers without tearing them—that’s it! These voluminous, cute floral decorations also look great when you mix and match different colors.
Rose petals
How about using rose petals to create a gorgeous surprise coordination? It might be an idea more suited to women than men, but you can use it in many situations—scatter them on the table or float them in the bath.
If you’re renting out a hotel room for a surprise decoration, covering the entire bed with petals could be romantic too.
Cleaning up afterward can be a hassle, but it’s sure to be appreciated—a perfect mood-setting decoration item.
Message on the window
This is a decoration where you write a celebratory message on a window.
Because it’s a display that appeals outward, it gives the impression of a sort of preview of the celebration for the guest of honor.
It’s a simple idea—just drawing messages or pictures on the window with a pen—but when the light hits it, it creates an even more festive atmosphere.
In addition to pen decorations, incorporating stickers can also result in a cohesive look.
If it’s difficult to draw directly on the window, you can enjoy variations like writing the message on an acrylic panel and attaching it to the window.
Giant Flower

When it comes to decorations, floral motifs are a classic choice.
If they’re large and three-dimensional, they’re likely to draw even more attention.
Giant paper flowers like these can be made easily using copier paper.
What you’ll need: thick paper or cardboard for the base, copier paper for the petals, and a hot glue gun to assemble everything.
Inspired by dahlias, the finished piece has a beautifully spread-out look—that’s a big part of its appeal.
Since the petals are built onto a base, you can use that base to mount the flower on a wall.
tassel garland

If you want to create a stylish birthday party with ease, tassel garlands are a great choice! If you’re thinking about decorating a wall for a birthday, definitely use this as a reference.
All you need are 12 sheets of tissue paper in three similar colors, some string, and masking tape—so it’s budget-friendly, too.
To make them, stack the tissue paper, fold it in half, and cut it into tassel strips with a craft knife.
Next, open up one sheet and roll it up to form a tassel.
Make 12 of these and tie them onto a string, and you’re done.
It’s an easy way to instantly brighten up a room!
Honeycomb ball

The honeycomb ball with a three-dimensional, flower-like spread is spherical, which makes it easy to use for decorations.
You can make it easily with just two sheets of origami, so why not make many and use them to decorate various places? The process is simple: use a compass and scissors to cut the origami into circles, then glue them together.
You can also enjoy different arrangements, such as combining origami of different colors or stringing the finished honeycomb balls together with thread.
Balloon garland

Using balloons for decorations can create a festive atmosphere thanks to their three-dimensional look.
A key point is that the overall impression changes depending on how you combine several balloons.
Choosing specific colors for the base balloons or adding plant motifs can give a natural appearance, which is also a fun touch.
By paying attention to additions like ribbons and stickers, you can make the arrangement as glamorous as you like.
It seems suitable for decorating various places, such as wall displays or table settings.
photo garland

How about making a photo garland for a birthday surprise or decoration? If you use photos of the birthday person, it’ll be a surprise and, above all, an unforgettable memory! Edit your favorite images with an app, print them on thicker paper, and cut them out.
Just stick them onto a string, and it’s easy to make—even beginners can do it.
You can also print photos of the birthday person or the date of the birthday! If you decorate the room nicely, it might even get attention on social media.
Give it a try for inspiration!
Balcony Café

Isn’t the stage for delivering a surprise just as important as the item itself? Anyone would be astonished if a familiar place suddenly took on a different atmosphere.
This idea is about transforming a home balcony into a stylish café-like space.
Use a wooden table and chairs, a reed screen to soften the sunlight, and plants on the table to create a café-like look.
It’s essentially about setting the stage for the surprise; by placing café-inspired dishes here, the balcony café is complete.
paper fan

How about using “paper fans” that look luxurious even on a small budget for birthday decorations? You can easily make them with just three sheets of construction paper from the 100-yen shop, so it’s perfect if you’re short on time before the big day! Score the paper at 2 cm intervals, fold it in half vertically, and crease the center.
Make three of these in the same way, connect them, and accordion-fold along the score lines.
Tie the center with fishing line, spread out the accordion, and secure it with clips—and you’re done! They make lovely decorations whether you hang them on the wall or suspend them from above.
