Leather case for iPhone 4

So this is an iphone 4. Since I can't bring myself to buy a case for my phones, I have figured out a few ways to make them. This one is from leather. I got this phone because of the materials really -- they had me at glass and stainless. That and the camera. The images it takes are really amazing actually. Apparently there is supposed to be a signal attenuation problem with the new iphone when it's touched in a certain place. I can't seem to really make mine do it, but with this case it becomes a non issue anyway.

This is a detail of the well-protected corner.


Here you can clearly see the way each stitch hangs off the edge. There is a tension line that is trapped there and used as a draw string.

There are actually two tension lines. One for the front, and one for the back. As I was working with the leather, it was clear that it was going to need some kind of non-stretch solution for the main dimensional elements of the case. I used two super-thin dyneema lines.


Here you can see the 3 dashes along the side where the two lines get woven into the leather. This is so they can be losened when the case needs to come off which is not very often.



The scrap shows the corners that had to be cut. 8 tiny pieces of leather each had to have a bevel to sit flat against the face of the phone.



As far as the sewing went, it was pretty fiddly. I used a darning foot which is a tiny round foot for the machine. It's normally used with those clampy wooden rings that we used to see in people's houses back when they made stuff -- sniff. Anyway, this foot works well for the leather because it's tiny, and doesn't actually make contact with the base plate of the machine. There is a gap that it leaves that is just about the right height for the thickness of the leather, so you don't have it pressing down super hard. I have an industrial machine, but i didn't even have a chance to use the motor. I just turned the hand wheel with my hand. Each stitch is hand-placed.

Hand-tied iPhone Case

After resisting the urge to buy a case from the at&t store - I have a strong dislike of retail these days, I made this iPhone case using some scraps of kitesurfing kite bridle line. I figure it beats buying yet another thing with lots of packaging. Since having knots in this stuff in this context wouldn't work, I pierced through with a bridling tool and used spectra to bind it at the key points. This protects it well from being dropped on the corners, and stays out of the way of the controls and the invisible sensors on the front of the screen that sense brightness and holding it up to your face. Second gen might be sewn at the white points using the machine.




So, I couldn't stand it. I went through and replaced all the spectra with bar-tacks done with the sewing machine. Here is the design all cleaned up and nice looking.
