I have had my cell phone's droped, smashed and the screen broken in my bag. So I made this to protect it.

Step 1: Materials.

What your going to need:
1. A Sharpie.
2. Scissors.
3. Your choice of tape.
4. Cell Phone.
5. And of course, Cardboard.

Step 2: Sizing.

Now that you have your materials, you want to start on the case. Put your Cell Phone on the cardboard, and draw an out line slightly larger than the phone.

Step 3: Cutting.

Start the cutting of the out line.

Step 4: Now for the Back.

Now your going to want to cut out the back so make a design of your choosing. I like this design so I'm going to show you it.

Follow what the picture's show below.

Step 5: Bending

Now so the "lid" can go over start bending it to a "loose" bend.

Step 6: Middle Slit.

No you have to start the center piece. For the phone I'm showing you which is 3/4" I made it 1". Then you need to bend it to the shape of your Front or Back peace. Cut off excess if needed.

Step 7: Putting It Together.

Start Putting it Together.

Step 8: Adding Personal Touch.

After you are done putting it together you can add your own personal touch. For me I covered it in Duct Tape for a kinda shiny look, but you can do what ever you want.
