Paper is again my favorite tool to make new things. This time it was a wallet for me. :) It was so simple to make and its absolutely comfortable to carry. But next time I make one, I should see to that I get a nice water proof paper. ;)I have done a pen drawing butterfly on the wallet to make it look interesting. 
This would be the front side of the wallet.

It can easily hold a lot of money and cards too. :)
