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.

Wow. Loved it :)
I'm soon gonna do it. Thanks for this awesome Instructable.
HollyMann (author)  sumers2 years ago
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.

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)  moseph2 years ago
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!

Thank you so much Jessie!
Great idea and instructable! Well done indeed!
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.
HollyMann (author)  Tarun Upadhyaya2 years ago
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!
