Introduction: Real Stone-Covered IPhone Case

This Instructable will guide you through the simple process of making your own real stone-covered cell phone case! Your phone will be well-protected - probably better than any commercially-sold case around!

Step 1: Materials for Stone Phone Case

Materials Needed:
  • Plaster of Paris & Disposable mixing bucket or bowl & mixing utensil
  • Modge Podge & Paint Brush to brush it on
  • Small Stones (I dug out all of mine from my front yard near my flower garden)
  • Basic Phone Case Shell (Simple phone case - nothing fancy)
  • Tacky Glue or some other type of Craft Glue
  • Disposable Gloves (optional)

Step 2: Wash Stones & Prepare Plaster

First, wash all of your little stones the best you can. I put them in a colander and washed and rinsed them with hot water. Next, you will need to prepare the Plaster of Paris. I used one cup of Plaster of Paris and a half a cup of water. I mixed that together and every few minutes would mix it again to check the consistency. It takes about 30 minutes for the plaster to set - but this can vary more or less, so it's important to check it by mixing it. You can't use it when it's too watery. But once it's thicker, at a consistency similar to frosting, you can then use it.

Step 3: Spreading the Plaster & Placing Stones

Once the plaster is ready, take your spatula and spread it on like you would icing on a cake! Be sure to have a thick enough layer - a quarter of a inch is good. Be careful to avoid getting it on the sides of the case (unless that is the style you are going for). Either way, avoid areas where there are buttons on the case. Once spread, then take those stones and drop them onto the phone or place them however you like. But, work fast enough because the plaster will dry! Once you have it how you like it, you'll need to let it sit and harden.

Step 4: Glue and Modge Podging the Case

At this point, I had an issue when making my case. It dried beautifully and the plaster and stone cover just slipped right off of the plastic shell it was on. Please check if it has truly adhered or not before proceeding. If not, then you will need to glue the plastered slab of stones (the cover you made) onto the plastic phone case.

After that, take out your Modge Podge and paintbrush, and spread the Modge Podge all over the phone case. Spread it in between the stones and also onto the sides of your case. Be sure to clean up any areas that seep into the inside of the case. It's important to spread it on the sides of the case as well as the top - to really secure it and bind it to the case.

Once dry, you'll notice that the Modge Podge has given your case a nice shiny beautiful look. Feel free to do several layers of the Modge Podge if you want your case even more solid.

Wow. Loved it :)
I'm soon gonna do it. Thanks for this awesome Instructable.

HollyMann (author)sumers2013-05-24

Oh good!! So glad you like it! I've been using mine for a while -dropped it too - still strong and fine. Must use the modge podge though to make it more flexible and less braky.

Your iphone rocks

Tracy_Marie (author)Arghus2013-05-21

Ha! Ha! "Rocks". Like that.

HollyMann (author)Tracy_Marie2013-05-24

You rock also!

capnjg (author)2013-05-23

That is so creative. I wonder if it would work on the hood of my car or maybe a T-shirt or maybe my underwear?!

HollyMann (author)capnjg2013-05-24

You have to try it and let us know!!! :) haha the car would work! Underwear - ahhh...the not the best idea ;0

totszwai (author)2013-05-21

Because the phone is not heavy enough. Gotta make it heavier...

mclare50 (author)2013-05-15

this is a great idea, and it looks so cool!!!

HollyMann (author)mclare502013-05-15

Thanks so much!

elizabeth1616 (author)2013-05-14

I love this idea

Horef (author)2013-05-11

That would help allot finding it after dropping it :D

moseph (author)2013-05-09

This is a cool idea, but how well has the plaster stood up? I am surprised it doesn't crack over time. Wouldn't a more flexible adhesive be more durable? Silicone or something?

HollyMann (author)moseph2013-05-10

Good question!!! Well, since I have several layers of modge podge over it (including the sides) it has not cracked. I've pulled it on and off a lot and even dropped it. The modge podge has made it a bit pliable or flexible. I'm not sure how well silicone would work or how fast it dries. But, modge podge is a definite option if you make it thick enough on the bottom. That would work for sure and keep it more flexible!

Shoja.Iran (author)2013-05-10

It's cool, but If imma cover ma iPhone 4 it makes it more heavier :D

HollyMann (author)Shoja.Iran2013-05-10

Yeah it does definitely add a little weight!

lindarose92 (author)2013-05-09

This is such a great idea, I love it!!

HollyMann (author)lindarose922013-05-09

Thanks Linda

Penolopy Bulnick (author)2013-05-09

Neat idea! It would be fun to do this with stones or shells collected on a vacation. Homemade souvenir :)

For sure

mikeasaurus (author)2013-05-09

The Mod Podge coat really makes it pop, this looks great!

HollyMann (author)mikeasaurus2013-05-09

Thanks Mike! It did make it nice and shiny!

Jessie Marie (author)2013-05-09

HollyMann (author)Jessie Marie2013-05-09

Thank you so much Jessie!

SlickSqueegie (author)2013-05-09

Great idea and instructable! Well done indeed!

Tarun Upadhyaya (author)2013-05-08

I know the secret of 100 stones :D. Very cool & creative Holly. Thanks for sharing. Sometimes I wish to study back again but in a Design school.

Hi Tarun - thanks for the comment! You studied software architecture? I am in school now taking a lot of art classes - just learned about Industrial Design and want to go that route while I still can (not getting any younger here)...but will need to relocate. Tarun you have great style and I love your creations...even without schooling - seems like you have the passion to do something with it!

I am just a computer science graduate but I its been 14 years since I am in IT and I chose the software architecture path, so that makes me an Architect. I wish you all the best for your future Holly, you inspire me and whenever I make a post here, I always come back to see if you have commented :). Thank you so much Holly.

Thank you Tarun! You inspire me too with your passion for creating things and the amazing things you're making - I really like to see what you're making!
