I SUGGEST CLICKING THE PHOTOS TO MAKE THEM BIGGER TO SEE A BETTER EXAMPLE.
Mine is quite bigger, because it fit an iPod classic and the headphones. I suggest sewing on the little felt screen and the selector before sewing up the sides, just make sure you are accurate and it will make everything a lot easier. Also, I decided to line mine with the fabric from a ripped up t shirt i had to not only make it more reliable but also to protect it better. the button slot i made just through the felt and not also through the liner so the iPod was protected from that as well. I tried to upload a photo of what the back looked like closed but it would not let me and i'm too lazy to take another. This is my twist on the project.
