You can use the card holder to hold any DinA5 (148mm x 210mm) sheet of paper. It can be a menu, a list of names or a seating plan. Use a DinA4 (210mm x 297mm) or similar sized sheet of paper and fold it in the middle. The paper should be a bit thicker than the usual printing paper in order for the card to stay upright. Make sure the tower in the middle is in between the two sides of the paper.
Happy Printing!
