Let me show you how I made my phone case from things just lying around my location (mostly junk) without spending a dollar..
Step 1: Gathering Your Materials
I will just list down the materials that I used .
Some nylon rope I picked up
Welding rod (made to an awl)
Wooden analog for phone(wooden side of a broken drawer)
Reflector strip (from an old coverall)
Step 2: Harvesting and Cleaning the Leather
I got my leather from my old boots (I received a new pair). I just cut the boots and washed the leather with some detergent and water.
While damp I stuck it under a book and put some weights on top to flatten it.
Step 3: Forming the Leather
Wrap your leather with some rags and dry it under the sun. This will be your front part for your case
Step 4: Cutting the Pieces
Mark your leather where you will cut it (depends on the size of your phone) and leave about 1/4 inch in all sides for stitches.
Do the same for another piece of leather by tracing your phone on it. Leave about 1/4 inch as margin for stitches on all sides and cut it. This will be the back part of your case.
Step 5: Punching Holes, Stitching the Bottom and Adding the Puller
After punching the holes I started stitching the bottom part of the case. I used some nylon strands from a nylon rope.
You can also add your ribbon ( I used a reflectorized strip) on the inside of the case. I glued it and stitched it on the wrong side of the front piece and made a slit for the puller on the back piece. I also lubricated the strip with vaseline and wiped the excess off. This will allow you to lift the phone out of the case when you pull the ribbon. I just copied the design from a cheap phone case.
For the stitching part,I just did a simple continuous stitch two times;, once on each side. You can just google some techniques..
Step 6: Stitching the Sides and Adding the Puller
Attach the puller on the ribbon. I used a small leftover leather from the boot.
Step 7: Test Fit
If it is too tight, dampen your leather and insert the analog until it dries. It will stretch the leather and give you that snug fit for your phone.
Step 8: Adding Minor Details and Polishing
I did a cut on the front part to expose the camera. I gave one to my friend since we have the same phone.
I made another one for myself where I added a sort of belt clip made from an old keychain and a welding rod. I also added a volume rocker on the side so I can adjust the volume when listening to music without removing the phone from the case.
For the volume rocker, I used a small strip op leather, dampen it and used the head of a two kinds of screws: (+) (-) to make an impression on the leather. I highlighted it using some correction pen and glued on the side to where the volume controls would be.
I used Vaseline for polishing and it worked great.
Sorry for the picture orientation. I uploaded this using my phone and I can't change the orientation. (Changed pic orientation and reuploaded)
