I’ve been thinking of making a magic trick, but I need to create some customized cards. Not a full 54 card deck, but around 4-5; like a packers worth of cards. How or where does one go about making custom fronts and backs for cards? Is there a website that does this? If you do this on your own, what programs would you need to do this? If you were to research marked card methods, are there any resources for that?
