Can someone please tell me how to properly use the checkbook wallet? Got one as a gift. Link of pic attached: http://www.brooksbrothers.com/IWCatP...lt_color=Brown The right side of the wallet is obvious..but the left side is a bit interesting. And here's where i'm lost: Where exctly does the check suppose to do? in between the flap? or the last hard page of the check fits in between the flap???
