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.

Once the whipped base is complete, decorate it with your favorite parts, like candies or animals.

Finally, attach color sprinkles and beads to finish.

Smartphone case made of clay

Clay-made smartphone cases are too cute

Smartphone case made of clay

This is an original smartphone case made by customizing clay you can buy at a 100-yen shop.

Use a toothpick and a ruler to create clay parts in any shapes you like.

Attach them to the back of the phone case using a top coat, then finish by brushing decoupage glue over the top.

Once the liquid dries and the clay is secured, the case is complete.

You can use a clear case or prepare a phone case that matches your clay design.

By getting colorful clay, you can enjoy creating a variety of designs with this smartphone case idea.

[Resin] Dried Flower Phone Case

I tried making a smartphone case with resin ♡ Handmade creator / Tutorial video / Mimosa / how to make

[Resin] Dried Flower Phone Case

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.

[Resin] Perfume Bottle Smartphone Case

[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

Let's make a simple original smartphone case with TinyTan ♡

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.

Fluffy smartphone case

DIY: Fluffy Smartphone Case — Easy Handmade Fuzzy Phone Case DIY

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.

Smartphone case with masking tape and stickers

[Original Phone Case] An easy-to-make case using just washi tape and stickers ☔️✨ #handmade #washiTape #maskingTape #phoneCase #Cando #100yenShop #stickers

Smartphone case with masking tape and stickers

Here’s an idea for an easy DIY original phone case you can make with masking tape and stickers you already have at home.

Cut a piece of thick paper to fit your phone case, then simply decorate it with masking tape and stickers—that’s it.

Because the paper sits inside the case, you can swap the design anytime to match your mood.

You can also have fun decorating the outside of the case with flake stickers, beads, or glitter.

Try alternating several types of masking tape, or choose a seasonal or event theme to create your own one-of-a-kind phone case.
