The easiest way to get started is to either use Photoshop, or go with Strange Eons 3.
Photoshop:
Vardaen has created a set of templates that you can use. You can download the templates via the link below, and work with them in Photoshop.
Strange Eons 3:
But if you are lazy(like me), then I will suggest that you use the wonderful program called Strange Eons 3 located HERE. It has templates you can download for different games, and it makes it really easy to get started creating adventures. Once you have created something you feel comfortable showing off, then you can write us at ” admin @ arkhamcentral.com “, and we will be more than happy to display it at ArkhamCentral. For printing you can use your own printer, or use a printing service .... below you will find a few suggestions. drivethrucards.com makeplayingcards.com printerstudio.com
