Let's make a DIY phone case! A collection of simple and cute ideas (1–10)
Deco whip smartphone case
Here’s an idea for a smartphone case you can make using “whip cream” that lets you enjoy the feeling of decorating sweets.
Pipe fluffy whip onto the phone case to create the design.
You can use deco whip from a 100-yen shop, or make your own from silicone.
Once the whipped base is complete, decorate it with your favorite parts, like candies or animals.
Finally, attach color sprinkles and beads to finish.
The result is a girly smartphone case overflowing with a cute, candy-shop vibe.

Here’s an idea for decorating a smartphone case with dried flowers that soothes with its vibrant colors.
Apply resin evenly to the back of a clear phone case to create a base, then use tweezers to arrange dried flowers on top.
The key is to consider the placement and balance of the leaves and flowers as you decorate.
Decide on the arrangement before the pieces set in place.
Add glitter or beads for extra sparkle, and finish by applying another layer of resin.
Once it cures, your phone case is complete.
Smartphone case made with stickers
Here’s how to make a smartphone case that you can customize using stickers you already have at home.
Prepare a clear-backed phone case and cover it completely with stickers, leaving no gaps.
Trim off any parts that stick out from the phone or any unwanted sections, then apply a liquid with glitter or beads to the outside of the case to blend it in.
Choosing a case with extra thickness on the back will give it a more three-dimensional look.
It’s also a fun idea to create one with a theme based on an anime character or your favorite idol’s illustration.

[Resin] Perfume Bottle Smartphone Case

Let me introduce a smartphone case inspired by a perfume bottle.
This design uses slender beads to outline the bottle shape, then colored resin is poured inside to create the look.
You can make several colors for a gradient effect, mix in sequins or glitter powder to boost the sparkle, and express the “perfume” in any style you like.
Of course, you can also shape the bottle itself however you prefer.
Adding embellishments like bijoux or ribbons makes it even lovelier.
It’s a stylish idea that’s perfect as a gift, too.
A smartphone case with a remade label
This is an original smartphone case made by reusing labels from plastic bottles.
Cut a piece of design paper to fit the size of your phone case, then attach parts cut out from bottle labels.
Decorate the cover with masking tape or sticker flakes, and trim off any excess.
After sticking the paper on from the inside, your original phone case is complete.
Since you’re using a clear case, it’s also recommended to make one by attaching not only label designs but also merch of your favorite idol or character.
wallet-style smartphone case
I’d like to introduce a way to make an original, folio-style smartphone case that fully protects your screen—perfect for anyone looking for a wallet-type case.
Using a folio case from a 100-yen shop and your favorite fabric, you can make it in just a few simple steps.
First, cut a clear file to match the shape of the folio case, then cut your fabric with a bit of extra width.
Attach double-sided tape and adhesive to the outside of the case, and carefully apply the fabric while paying attention to the camera opening.
That’s it—done!
Fluffy smartphone case
If you’re looking for a smartphone case with a warm, cozy feel, I recommend a fluffy handmade case.
Choose a yarn from the 100-yen shop that creates a puffy, textured fabric.
The key points when making the case are to neatly cut out the camera area and to trim the yarn slightly shorter on the inside of the case so it doesn’t spread.
Once you’ve cut the fabric to your phone’s size, attach it to a case lined with double-sided tape on the outside and sides of the phone, and you’re done.
