Some supplies you'll need.
Choose any fabric you like, it can be done with pretty much anything.
Take your old iPhone case.
Lay it on the fabric and use the knife to cut along the sides.
Once the fabric is cut, trim the edges to insure a tidy, clean look.
Use a glue gun to glue the fabric onto the back of the iPhone case you've chosen.
Clean up and cut off the excess glue that may have dripped onto the case.
Now you have a faux fur iPhone case!
