Herd Mentality Card Holder

Got Herd Mentality as a birthday gift and noted straightaway that the card holder was very tight (couldn't get the cards out) so decided to make my own. Took much longer than expected what with different designs but I think I got there in the end. The actual card holder is a one-colour print, but the front and side panels are a three-colour print (preferably pink and black for the patches).
