How do I go about making custom components for Cosmic Encounter fan-made elements? Hi all, this question is mostly directed at those with experience in making and printing fan-made expansions for any of their games. What is the best approach to making cards that are close to indistinguishable from the official components?

For example Cosmic Encounter uses Flare cards and Alien Power cards which I would like to add some fan-made powers. My first thought was to buy another copy of one of the official expansions and perhaps paste sheets of paper with the fan powers onto them, but I don't think the end product would actually look that good. What other approaches can I take?
