The CrocodileCash Paper Wallet doesn't need to be something supper fancy
it could be something simple with the logo in the center
like

(note: this format makes it so you can fold the paper in to 3, so it more easy to store/hide)
maybe with some text/guide on it how processes work, what to do ect ect
and recommendition to put some
clear sticky plastic film on the paper to
preserve the printed ink
well, i assume others could have a better suggestion the me too around here

works similar although you can also download it to your own PC and generate offline for the supported currencies, you can get added to the list by filling this out but it may never happen
Here is how to add a new currency to WalletGenerator.net. This how-to is sufficiently detailed that you don't need to be a developer to follow it.
