I finally got an iPhone! But then I needed to keep it safe while it’s in my purse or if it happens to fall out of my coat pocket while I’m walking. This case has a layer of cardboard on each side of the phone for extra protection and it’s big enough to hold an iPhone 4/4S that has a rubber case on it.

The measurements I used for the pattern are based on the width of my phone with a protective rubber case on it (as seen in the above photo).

Please continue on to see the pattern and tutorial.

(This is the first time I’ve done a pattern or tutorial so please be gentle with your comments, although I’d appreciate some helpful ones.)

I used:

  • half a meter of Michael Miller CX4927 Cocoa (100% Cotton)
  • matching thread
  • 1 plastic button
  • 2 pieces of thin cardboard traced from iPhone
  • fabric chalk pencil

I’m currently just hand sewing my projects. For this project, I used a simple running stitch and a whipstitch.

1. Prepare your fabric. I purchased half a meter of fabric for this project but had quite a bit leftover, so you could probably get away with less than that. Fold your fabric down in two layers, patterns facing out. (See photo.) Lay your fabric out on a flat surface as smooth as you can.

2. Using fabric chalk, copy the pattern over. You can print it off and trace it if you wish. It’s super simple to copy over, you just need to try to keep your lines straight. I used the raw edge of my fabric and the selvage edge as a guide. Pin your fabric down before cutting to avoid the material sliding around on you.

(One more thing: I’m Canadian so I use centimeters. Click here if you need to convert cm to inches.)

3. Flip both pieces of material over and pin them together, like in the photo below. The patterned side of the fabric should be facing inward and facing each other.

4. Use a running stitch along every side but the bottom. (If you’re using the pattern, use a running stitch along every except for Side C.) You should then have something that looks like this:

5. The cardboard I used for this was cut out from a snack box. Doesn’t matter if there’s anything on either side. I traced the shape from my iPhone (again, with the rubber protective case on) and cut them out. They don’t have to be identical or have smooth edges.

6. Turn your fabric right side out so the patterned side is on the outside. Mark a line down the middle of your material and do some running stitches down the middle. This is where we will fold our iPhone case in half.

NOTE: I did make a booboo when sewing this particular project. I waited until later to add the button. Mistake! Now would be the best time to add the button. Fold your case together, flip the top flap over and decide where to put your button now, before the cardboard goes in. Or you can continue on with my directions and just sew through the cardboard like I did. I just had to use a bigger needle. Not a big deal, but I thought I should mention it.

7. Put a piece of cardboard into the two separate compartments we have made inside our case. Tuck them down in there as far as they will go.

8. Fold up the bottom opening by about 2 cm and using a running stitch across to seal the cardboard inside.







9. Fold the case in half (covering what you just sewed in step 8). This should bring side C and B together. Use a whipstitch to seal the bottom and side. Stop sewing when you reach the top flap.

10. Decide where you want to put your button and sew it in (unless you already did, like I recommended earlier in this tutorial). Then cut a hole in the top flap and line it using a whipstitch.

And you’re done!

(I’m going to cover my butt and say that I cannot by any means guarantee that this case will protect your iPhone from damage. This is more to protect your iPhone screen from getting scratched by loose change when it’s in your purse.)
