In this Instructable, I will show you how to turn any old trousers (Yes, the title says Levi's, but this works with any other trousers, too - I don't even wear jeans) into an iPhone or iPod Touch jacket.

Step 1: What You Need

Here is a list of what you need:

1) Old trousers. Did I mention that they aren't wearable any more when they hold your iPhone? Now you know.

2) Scissors. To cut out the pattern.

3a) Needle and thread. Don't use a thin thread - it should be something that doesn't rip easily.
or
3b) A sewing machine.

4) White chalk or something to draw on the cloth. You can erase white chalk, that's why it's good, but you can also use a simple pen. You won't see the lines any more, anyway.

5) An iPhone or iPod Touch. That your jacket is worth being made.

Step 2: Choosing the Right Part

Choosing the right part is easy when you use a simple Jeans without any pattern or nice, little images on it. In my case, I choose the wing of that falcon to make it look vector-like.

You will need a rectangular free space of 28cm x 10cm (11" x 3.9"). This does also mean, no pockets or anything in this space. I had to cut away the clip of a pocket, as you can see on the picture.

Cut it out very generously.

Step 3: Copying the Pattern

Copy the following pattern on the back side of your cloth. The top rectangle will later be the front of your jacket, so be sure that the design on the other side fits within the rectangle like you want it to be.

Step 4: Sewing the Top

It's time to sew the jacket together. You can either use needle and thread or a sewing machine.

1) Make a valley fold on the top line, so that the 'nice' side is on the outside.

2) Sew 2mm (0.1") under the folding line. If you don't know how to sew (You have an iPhone - You don't need to know), the first picture describes it. Make a knot with the thread at the beginning of the line, then sew until the end of the line and make another knot (No, you don't see the line anymore - It's on the inside. Use your imagination.).
Important: The side where you only see a dotted line (On the first reference picture it's the side on the bottom) has to be on the 'nice' side (the outer side).

When you're done, it should look like in the second picture. From the other side (the inner side), it should look like the third picture (At least when you rotate your stuff 90 degrees).

Step 5: Sewing the Sides

Make a mountain fold at the line in the middle, so that you face the 'ugly' inner side. Both lines that were already sewed should cover each other. If not, forget about the line in the middle and make your own (It should at least be very close to the original line).

Then sew along the remaining two lines. It doesn't matter on which side the dotted and the continuous sewing lines are.
If you want to have a flap like in the intro-picture, you have to sew it in now. Remember that the flap has to be on the inside of the pocket, because it will be turned inside out at the end. So just lay it where the rectangle in the picture is and sew along the line.

When you are done with both lines, you can cut away the rest of the stuff (about 5mm / 2" next to the sewing lines)

Step 6: Finishing

You may want to cut away a few ends of thread that don't look nice.

What I also recommend you to do is sewing a few times around the two edges on top to make the edges more stable and give the jacket the look of something expensive. It doesn't look nice when the stuff is tattered at the edges later.

What may also help is a bit of glue over the threads next to the edges. This prevents getting stuck with the volume-switch of the iPhone in the threads.

Step 7: You're Done!

Urgh, it turned out ugly... Probably not, because it has to be turned inside out now. Gently press the bottom out of the hole on top of the jacket.

Congratulations, now you are done and your iPhone doesn't have to sleep naked anymore.
