Lately I've been thinking of combining my wallet and my Moleskin Volant Mini, but I haven't found exactly what I'm looking for yet. What I am thinking of is some sort of leather case that opens up like a book, has a place to put the moleskin on one side and has sleeves for credit cards, etc. on the other side and a place for cash. If no place for cash, I could always start using a money clip I suppose. Total size would have to be something small enough for back pocket carry. If anyone has seen anything kind of like that, please let me know.
