I took a deck of cards and Hollowed out a space inside to fit my Ipod Nano. Then I fitted the Ipod inside and mounted a card on the Back and one with a viewing hole on the front.. You can even still use the click wheel and its easy to find because it lines up right underneath the bottom circle on the card back design....
