I've seen some poker cards made of fondant and gumpaste. How do you make the print on the cards, hearts, diamonds, etc..? Thank you in advance...

If I were going to do them I'd put edible images on gumpaste

I like the printable way, but I've seen people use heart, spade, diamond and club cookie cutters that are small enough for cards. You can cut the shapes out of Fondant or GP.

I like EIs too
